📦 Automate Steam Login Process

Baseurl: https://www.steamwebapi.com/steam/api/steamloginsecure 💬 **What this endpoint does:** - Automates your Steam login process, including for trading, market, and other Steam Community features. - With the `steamLoginSecure` cookie, you can use our Trading API and build easy-to-use trading bots, market trackers, and more. 🛠️ **How to use:** There are **two ways to authenticate**: 1. **Username + Password Login** - Send a POST request with your Steam `username` and `password` in the request body. - If your account is protected by Steam Guard, include the `code` parameter from your mobile authenticator. 2. **Refresh Token Login** - Instead of username/password, you can provide a `steamrefreshtoken` (JWT). - This token is returned after the initial login and allows you to request a fresh `steamLoginSecure` cookie without needing to re-enter credentials. 🚨 **Important Note:** - Do **not** provide both login credentials and `steamrefreshtoken` at the same time. - One of the two options must be present, not both. 🌐 **Additional Info:** - The login process is handled securely. No password is stored server-side. - This endpoint is ideal for building: - Trading bots - Market analyzers - Automated session checkers 📦 **Response:** - On success, you will receive the following cookies: - `steamLoginSecure` – required for authenticated Steam Community actions - `sessionid` – required for most web interactions - `browserid` – identifies the browser/session - `steamrefreshtoken` – reusable token to fetch new `steamLoginSecure` cookies later 🕒 **Token Lifespan** - The `steamrefreshtoken` is typically valid for **up to 6 months** - It can be used repeatedly to retrieve new `steamLoginSecure` cookies without logging in again.

Parameters

Geen parameters naast je API-sleutel.

Request body

JSON payload containing the required parameters for Steam login. There are two ways to authenticate: - Via `username` + `password` (optionally if Guard is active you need MFA File then shared_secret as `code` - NOT GUARD CODE) - Or via `steamrefreshtoken` only ⚠️ You must provide either (username + password) or steamrefreshtoken – but not both.

GET /steam/api/items

🎯 Retrieve All Items with Prices - The Complete Steam Market API

Baseurl: https://www.steamwebapi.com/steam/api/items?key=YOUR_API_KEY&game=cs2 💬 **What this endpoint does:** - Retrieves comprehensive item data for Steam games (CS2, Rust, Dota 2, TF2). - Returns detailed pricing information from Steam Market and third-party markets. - Provides metadata including rarity, wear, StatTrak status, and more. - Supports advanced filtering, sorting, and pagination. 🛠️ **Features:** - **Multi-source pricing**: Steam prices, real market prices, buy orders, and historical data. - **Advanced filters**: Filter by price range, wear, item type, group, and more. - **Flexible sorting**: Sort by price, popularity, win/loss ratio, or randomly. - **Field selection**: Use `select` parameter to return only specific fields. - **Multiple formats**: Export as JSON, CSV, XML, or database statements. - **Currency conversion**: Convert prices to EUR, TRY, RUB, and more. 🌐 **How to use:** - Basic call: `GET /steam/api/items?key=YOUR_KEY&game=cs2` - Search items: `GET /steam/api/items?key=YOUR_KEY&search=AK-47` - Filter by price: `GET /steam/api/items?key=YOUR_KEY&price_min=10&price_max=100` - Filter by type: `GET /steam/api/items?key=YOUR_KEY&item_group=knife&wear=fn` - Sort by popularity: `GET /steam/api/items?key=YOUR_KEY&sort_by=soldZa` - Select fields: `GET /steam/api/items?key=YOUR_KEY&select=markethashname,pricelatest,image` - Export as CSV: `GET /steam/api/items?key=YOUR_KEY&format=csv` 📊 **Response fields explained:** - `pricelatest`: Current lowest Steam Market listing price. - `pricelatestsell`: Price of the most recent Steam sale. - `pricereal`: Current lowest third-party market price. - `pricemix`: Lowest price across all sources (Steam + markets). - `buyorderprice`: Highest Steam buy order price. - `sold24h/7d/30d/90d`: Number of items sold in the respective time period. - `points`: Market cap score (price × volume indicator). - `winloss`: Price comparison Steam vs. real markets (positive = Steam cheaper). - `releasedat`: Earliest known base-skin collection release date as a UTC object (date, timezone_type: 3, timezone: UTC), or null. Midnight is a presentation convention, not a known release time. Updated by a daily background command; not the first Steam listing or a variant-specific release date. - CS2 `only_new_items=1` or `true`: Missing items from all skin collections sharing the latest release date. - CS2 `with_preview_items=1`: Normal items plus the same missing latest-release items. Preview rows use normal IDs, collection in `tag7`, and `preview=true`; optional `description` preserves source text. `steamlisting` is inferred from a Steam economy image, without a live listing check. ⚠️ **Performance tips:** - Use `max` parameter to limit results (default: 50000). - Apply filters to narrow down results. - Use `select` to return only needed fields. - Use `production=1` in production to remove info fields.

Parameters

Naam Type Verpl. Beschrijving
key string ja Your API key for authentication. Required for all requests. Get your API key from Dashboard → Top-right corner → API Key section.
game string nee Game identifier. Each game has different item properties and markets. **Supported games:** - `cs2` (default): Counter-Strike 2 - Full support including real market prices - `rust`: Rust - Basic Steam market data - `dota`: Dota 2 - Basic Steam market data - `tf2`: Team Fortress 2 - Basic Steam market data
page integer nee Page number for pagination. Use with `max` parameter. - Page 1 returns items 1-50000 (with default max) - Page 2 returns items 50001-100000, etc.
max integer nee Maximum number of items per page. Lower values improve response time. **Recommendations:** - Use 100-1000 for web applications - Use higher values for data exports - Maximum: 50000 items per request bijv. 100
limit integer nee Alias for `max`, accepted for clients that use the more common name. Only applied when `max` is absent — an explicit `max` always wins, and sending neither keeps the 50000 default. bijv. 12
sort_by string nee Sorting order for results. ⚠️ **Performance Note:** Sorting can significantly slow down responses for large result sets. Use filters (`price_min`, `item_group`, etc.) to reduce data before sorting, or use the default `priceAz` for best performance. **Price-based sorting:** - `priceAz` (default): Steam listing price ascending (cheapest first) - *Fastest* - `priceZa`: Steam listing price descending (most expensive first) - `priceRealAz`: Third-party market price ascending - `priceRealZa`: Third-party market price descending **Win/Loss sorting** (Steam vs. Market price comparison): - `winner`: Best deals first (Steam cheaper than markets) - `loser`: Worst deals first (Steam more expensive) - `winLossAz`: Win/loss ascending - `winLossZa`: Win/loss descending - `winnerRandom`: Winners first, randomized within group - `loserRandom`: Losers first, randomized within group **Volume-based sorting:** - `soldAz`: Least sold items first - `soldZa`: Most sold items first (popular items) - `pointsAz`: Lowest market cap first - `pointsZa`: Highest market cap first **Other:** - `name`: Alphabetical by market hash name - `random`: Random order (useful for discovery) - *Slowest*

Historical database-missing items are not appended. The shared ByMykel catalog is refreshed by a five-minute background job. Preview IDs use the normal item ID algorithm; tag7 contains the collection name. steamlisting is inferred from a source Steam economy image, not checked live. Both preview options share the same fields and select behavior; preview always survives select.
only_new_items string nee Set to 1 or true for CS2 skins missing from the database in the latest skin-collection release wave. Every skin collection with the newest shared release date is included. Undated and future collections are excluded. Takes precedence over with_preview_items. Supports search, wear, item_type, item_group, item_name, collection_id, page, max and select. Uses the same preview fields as with_preview_items: normal item IDs, collection in tag7 and steamlisting inferred from source Steam economy images (not a live page check). preview=true survives select.
collection_id string nee Narrow only_new_items=1 or true by an exact ByMykel collection ID within the latest release wave.

📈 Get Daily Aggregated Price History for multiple Items

Baseurl: https://www.steamwebapi.com/steam/api/items/history?markets=steam,dmarket,skinport&game=cs2&key=YOUR_API_KEY 💬 **What this endpoint does:** - Aggregates historical price data for any items over time. - Returns daily aggregated data showing total worth and item count. - Uses the lowest positive daily close from exactly the requested markets. `steam` can be combined with third-party market idents. - Each request costs 1 credit regardless of the number of items. 🌐 **How to use:** - Send `items` as legacy market-hash-name strings or objects with `market_hash_name`, optional `phase`, optional `paint_index`, and optional `count`. - Specify selected market idents as a comma-separated `markets` value in the query or request body. The query value wins when both are provided. Omitting it defaults to Steam. - The endpoint returns daily aggregated worth after resolving the selected markets for every item and day. - Duplicate items in the array are counted separately (e.g., 2x "AK-47 | Redline" = 2x price). - For phase-aware objects, third-party prices must match the exact phase; Steam remains a valid generic candidate. - Before the first exact phase snapshot, phase-aware items use the lowest generic Doppler history from the selected markets. From the first exact snapshot onward, third-party candidates must match the phase; Steam remains generic. 📊 **Use Cases:** - **Inventory Tracking:** Track your Steam inventory value over time by sending all your item names - **Portfolio Analysis:** Monitor the performance of specific item collections or investment portfolios - **Watchlist Monitoring:** Track price trends for items you're interested in buying or selling - **Market Research:** Compare historical performance between different item categories or rarities - **Trading Strategies:** Analyze price movements for items in your trading pool

GET /api/assets

Retrieve CS assets with filters and pagination

Baseurl: https://www.steamwebapi.com/api/assets?key=YOUR_API_KEY 💬 **What this endpoint does:** - Returns over million CS assets (inventory- and market-related items) with flexible filter options. - Supports powerful pagination for large result sets. 🛠️ **Features:** - Filter by owner (SteamID64), weapon (def_index), skin (paint_index), float range, StatTrak, Souvenir, rarity, quality, origin and paint_seed. - Filter by exact market hash name (market_hash_name). - Filter only assets that belong to Steam profiles or only to market listings. - Filter assets that have stickers and/or keychains. - Paginated responses via limit and offset. 🌐 **How to use:** - All query parameters use snake_case naming. - Combine multiple filter parameters as needed (for example steam_id + def_index + min_float/max_float). - Use offset for pagination (for example offset=50 for page 2 with limit=50). - By default the endpoint returns a limited number of assets per request (configurable via the limit parameter). - Also reachable at the legacy path `/steam/api/float/assets` — identical behavior, kept for backward compatibility.

Parameters

Naam Type Verpl. Beschrijving
key string ja Your API key for authentication. Retrieve it from your Dashboard (top-right corner).
steam_id string nee Filter by SteamID64 of the owner, for example 76561198042843401.
market_hash_name string nee Filter by exact market hash name, for example "AK-47 | Uncharted (Factory New)".
def_index integer nee Filter by weapon definition index, for example 7 for AK-47.
paint_index integer nee Filter by paint index / skin ID, for example 836 for "AK-47 | Uncharted".
float string nee Exact float (wear) lookup, for example 0.030868796632. Matches the value at the precision you supply: the tolerance is one unit in the last decimal place you send, so a displayed/rounded float finds the stored asset (0.030868796631694) instead of returning nothing. Send more decimals to narrow the match, fewer to widen it — 0.030868796632 searches ±1e-12, while 0.03 searches ±0.01. Prefer this over min_float=X&max_float=X, which compares raw Float64 values and therefore misses rounded input.
min_float number nee Minimum float value (wear) inclusive, for example 0.00 for Factory New range start.
max_float number nee Maximum float value (wear) inclusive, for example 0.07 for Factory New range end.
is_stattrak integer nee Filter by StatTrak status (1 = StatTrak, 0 = non-StatTrak).
is_souvenir integer nee Filter by Souvenir status (1 = Souvenir, 0 = non-Souvenir).
rarity integer nee Filter by rarity tier. Typical values are in the range 1-6 (for example 6 = Covert).
quality integer nee Filter by item quality, for example 4 = normal, 9 = rarity-specific.
origin string nee Filter by origin such as drop, market-purchase or case-reward.
paint_seed integer nee Filter by exact paint seed / pattern number, for example 915.
wear string nee Filter by wear category code: fn (Factory New), mw (Minimal Wear), ft (Field-Tested), ww (Well-Worn), bs (Battle-Scarred). Case-insensitive.
phase string nee Filter by Doppler / Gamma phase, for example "p1", "p2", "p3", "p4", "ruby", "sapphire", "black-pearl", "emerald".
source string nee Filter by ingestion source. Examples: "inventory" (collected via /inventory endpoint), "csfloat", "youpin" (third-party marketplace scrapers).
asset_id string nee Filter by exact Steam asset id (inventory id) — useful for direct lookups.
date string nee Filter by calendar date when the asset was created. Accepts ISO dates (YYYY-MM-DD) or local format such as 31.12.2025.
sort string nee Sort order. Supported values: newest, oldest, lowest_float, highest_float. Default is newest.
limit integer nee Number of results to return. Default is 10, upper limit depends on your plan.
offset integer nee Offset for pagination, for example 50 for page 2 when limit=50.
only_steam_id integer nee If set to 1, only assets with a SteamID64 owner are returned.
only_market_id integer nee If set to 1, only assets without a SteamID64 owner (market listings) are returned.
with_stickers integer nee If set to 1, only assets that have at least one sticker are returned.
with_keychains integer nee If set to 1, only assets that have at least one keychain are returned.
with_items integer nee If set to 1, enrich each asset with the matching item record from the items database (joined by market_hash_name). The item payload is exposed under the "item" key.
with_profiles integer nee If set to 1, enrich each asset with the matching Steam profile (joined by SteamID64). The profile payload is exposed under the "profile" key.
format string nee Response format: json (default), csv, xml, html, gzip, zip, ndjson, mysql, mysql_with_table, pgsql, pgsql_with_table, mongo.

POST /api/assets/find

Batch CS2 asset ownership history lookup by float and/or paint-seed identity

Baseurl: https://www.steamwebapi.com/api/assets/find?key=YOUR_API_KEY 💬 **What this endpoint does:** - Looks up CS2 items by any combination of float, def_index and paint_seed, and returns the full ownership timeline of every matching physical item — each previous SteamID64 owner and each market listing in between, oldest first. 🛠️ **How identity matching works:** - A physical CS2 item keeps the same (def_index, paint_seed, float) forever, even as its asset_id and owner change on every trade. Send all three and you address exactly one item; send fewer and you get every item that fits. - Accepted combinations: `float` alone, `def_index` + `paint_seed`, or any mix of the three. `def_index` alone or `paint_seed` alone is refused — each would match six figures of rows, so the answer would be useless. - `float` is matched at the precision you send, so a rounded/displayed float still finds the stored value (12 decimals ≈ ±1e-12; fewer decimals widen the match). At least 6 decimals are required. - `paint_index` is an extra filter, never a search key on its own. - Field names are accepted in both spellings: `def_index` / `paint_seed` / `paint_index` as documented, and `defindex` / `paintseed` / `paintindex` as they appear in the response — so an identity can be copied straight out of a previous result. - Coverage is inherent, not a bug: an item only has history if this platform tracked it under a previous owner before. Items whose first owner is still the current one come back with a single owner entry. 🌐 **How to use:** - POST a JSON body: `{"items": [{"float": "0.030868796632", "def_index": 7, "paint_seed": 915, "ref": "my-id"}, ...]}`. - Every entry answers with `matched` (how many physical items fit) and `items` (one timeline each). A full triple gives `matched: 1`; a partial key can give many. - At most 25 items are returned per entry. `truncated: true` says more existed — narrow the key to see them. - `data` is always the same length as `items` you sent, in the same order. `ref` is optional, echoed back, and the safer way to correlate. - Pass `steam_id` (SteamID64) to state which owner in each timeline is the current one; when omitted, the newest owner segment is treated as current. - Malformed entries never fail the batch — they come back individually as `status: "invalid"` with a reason. - Credits: 1 per entry sent, regardless of how many items it matched (found, not_found and invalid all count).

GET /steam/api/float

🔍 Retrieve Float Information for an Item

Baseurl: https://www.steamwebapi.com/steam/api/float?key=YOUR_API_KEY&url=INSPECT_LINK 💬 **What this endpoint does:** - Retrieves float information for a specific CS:GO / CS2 item by decoding the inspect certificate in-process. - Requires either the `url` parameter (full inspect link) or the `certificate` parameter (raw hex certificate). ⚠️ **Important — legacy format no longer supported:** Valve discontinued the old inspect link formats `S{steamid}A{assetid}D{value}` (personal inventory) and `M{marketid}A{assetid}D{value}` (market listing) when they shut down the public Game Coordinator endpoint. Those links carried no float data on their own — they were only reference IDs, and float retrieval relied on a Steam GC roundtrip that no longer exists. **Any URL matching the old S/M pattern will return HTTP 406.** Only the new certificate format works. 🆕 **Certificate format:** The new format embeds the full item state (float, paintseed, paintindex, stickers, keychains, StatTrak kill count, name tag, …) as a hex-encoded protobuf payload right inside the inspect link. No external lookup, no bot, no GC roundtrip — the certificate IS the data. - Full URL form: `steam://run/730//+csgo_econ_action_preview ` - Raw form (pass via `certificate=`): `` (e.g. `49598AF087A6F948...`) 🌐 **How to use:** - Pass the inspect link via `url=` or the raw hex via `certificate=` — exactly one of the two is required. - Inspect links can be obtained from our Inventory API (`/steam/api/inventory`) — the `inspectlink` field there is always in the supported certificate format. - Authenticate with your API key.

Parameters

Naam Type Verpl. Beschrijving
key string ja Your API key for authentication. Retrieve it from your Dashboard (top-right corner).
url string nee Inspect link in the **certificate format only**. Example: `steam://run/730//+csgo_econ_action_preview%203C2CD7CEF39C8E...`. The legacy `S{steamid}A{assetid}D{value}` and `M{marketid}A{assetid}D{value}` formats were discontinued by Valve and **will return HTTP 406** — they no longer carry retrievable float data. Either `url` or `certificate` is required.
certificate string nee Raw hex certificate without the `steam://run/730//+csgo_econ_action_preview+` prefix. Example: `49598AF087A6F948...`. This is the encoded protobuf payload that carries the entire item state (float, paintseed, stickers, …). Either `url` or `certificate` is required.
production string nee If you run in production, please set this to 1. Default is 0. This is in future required, and if not set, you will get a warning.
format string nee Response format: json (default), csv, xml, html, gzip, zip, ndjson, mysql, mysql_with_table, pgsql, pgsql_with_table, mongo. Example: ?format=csv
pretty string nee Pretty-print JSON (set to 1 for json/gzip/zip formats). Example: ?format=json&pretty=1

  • 200 Request was successful, and the float data for the item is returned.
  • 402 Rate limit exceeded (daily or monthly).
  • 406 Inspect link is missing or uses a deprecated format. The legacy S/M-link formats (S{steamid}A{assetid}D{value}, M{marketid}A{assetid}D{value}) were discontinued by Valve and are no longer supported — only the certificate (hex) format is accepted.
  • 416 Service overloaded or unable to retrieve float information. Please try again later.
  • 417 Certificate could not be decoded — the inspect link or hex is likely malformed or corrupt.
  • 503 Certificate decoded but produced no usable item data (empty protobuf payload). The link is likely invalid or pointing to an item that no longer exists.
GET /steam/api/float/screenshot

🖼️ Generate Screenshot with Float Information

Generate a screenshot image with detailed float information for a specific CS:GO / CS2 item. The float data is decoded from the inspect certificate and rendered onto a customizable background; the response streams the resulting PNG directly to the client. ⚠️ **Same format rules as `/steam/api/float`:** only the certificate (hex) inspect link format is supported. The legacy S/M-link formats were discontinued by Valve and will return HTTP 406.

🔗 Generate a CS2 inspect-link from raw item data

Baseurl: https://www.steamwebapi.com/steam/api/float/create-inspectlink?key=YOUR_API_KEY 💬 **What this endpoint does:** - Generates a fully self-contained CS2 inspect-link from raw item data — the inverse of the `GET /steam/api/float` decoder. - Output is compatible with our own decoder, csfloat's inspect tool, and every CS2 client that opens the link in-game. - No Steam game-coordinator round trip — the certificate hex carries the entire item state. 🛠️ **Use cases:** - Mock inspect-links for UI development and screenshots. - Reconstructing an inspect-link when only the raw item data is known (backfill, migration). - Generating links for items that never existed in any real inventory. 🌐 **How to use:** - POST a JSON body with at least `defindex`. All other fields default to 0/empty. - `quality` is auto-derived from `stattrak` / `souvenir` flags if you do not set it explicitly (4 / 9 / 12). - `stickers` (max 5), `keychains` (max 1) and `variations` (max 5) accept arrays of objects with `sticker_id` (required) plus any of `slot`, `wear`, `scale`, `rotation`, `pattern`, `tint_id`, `offset_x`, `offset_y`, `offset_z`. - Response includes the generated `inspectlink`, the raw `certificate` hex, and a `decoded` round-trip — so you can verify what the link will produce when re-decoded.

GET /api/profile/risk

🚩 Score a Steam account for smurf / alternate-account risk

Baseurl: https://www.steamwebapi.com/api/profile/risk?steam_id=76561198042843401&key=YOUR_API_KEY 💬 **What this endpoint does:** - Scores how likely a Steam account is a secondary ("smurf") account whose inventory was handed over from another account, rather than built up on its own. - Answers the question anti-cheat, matchmaking and marketplace operators actually have: is this fresh-looking account really a fresh player? 🛠️ **What you get:** - `risk.score` (0-100) and `risk.level` (low / medium / high) as the overall assessment. - `risk.smurf.detected` — the boolean verdict, with its own score and level. - `risk.smurf.confidence` (low / medium / high) — how much is known about this account. A `detected: false` at `confidence: low` means "cannot tell", NOT "clean". - Guaranteed: `level: high` only ever occurs together with `confidence: high`. A thin-evidence account is capped at `medium`, so acting automatically on `level: high` never acts on a guess. - `risk.smurf.signals` — stable signal codes that fired: `round_trip_partner` (something left this account and came back — the strongest single indicator), `dominant_destination`, `bidirectional_partner`, `single_origin_dominant`, `bulk_acquisition_window`, `account_young_at_acquisition`, `origin_account_older`, `origin_account_inactive`, `limited_account_high_value` (a limited account — one that never spent money on Steam — holding a valuable inventory; supporting evidence only). - `risk.smurf.since` — the date the pattern starts, when one could be established. - `risk.smurf.summary` — a plain-language conclusion you can surface to staff. - `risk.smurf.linkedaccounts` — which accounts this one is linked to, strongest first. Per entry: `steamid`, a `profile` block with who that is (`personaname`, `avatar`, `avatarfull`, `timecreated`, `timecreatedat`, `loccountrycode`, `vac`, `tradeban`, `inventoryworthpricesteam`; null when the account is unknown to us), `matchscore` (0-100) and `matchlevel`, `share`, `direction` (incoming / outgoing / both), `roundtrip`, a `transfers` breakdown (received, sent, total, direct, viamarket), `firsttransfer` / `lasttransfer` / `windowdays`, and `reasons` — the plain-language evidence each score is built from, including what argued against it (a counterpart that trades with many different accounts, or still holds a large inventory, is dampened towards 0 because that is what a dealer looks like, not a second account). Empty when nothing links this account to anyone. 🌐 **How to use:** - Pass `steam_id` (SteamID64). Nothing else is required — the assessment is resolved entirely server-side. - Results are cached per account for several hours, so polling the same account is cheap for you and stable for your UI. - Credits: 1 per call, regardless of how much history the account has or how many accounts fed into it. They count against the same Profile allowance as the other Profile endpoints. ⚠️ **How to read the verdict:** - This is a strong probabilistic indicator, not proof of identity, and must not be the sole basis for banning or rejecting a user. - `risk` is a container: further risk types may be added alongside `smurf` later, so read it by key rather than by position.

GET /api/profile/trades

🔄 Trade history of a Steam account — who it traded with, which items, in which direction

Baseurl: https://www.steamwebapi.com/api/profile/trades?steam_id=76561198042843401&key=YOUR_API_KEY 💬 **What this endpoint does:** - Returns the observed trade history of a Steam account: every item handover we have seen, in both directions, with the account on the other side. - Reconstructed from inventory sightings of physical CS2 items, so it covers trades between players as well as items that travelled through a marketplace. 🛠️ **What you get:** - `data` — one row per handover, newest first. Per row: `direction` (`in` = the account received the item, `out` = it gave the item away), `partner` (SteamID64 of the other side), `seenat` and `senderlastseenat` (the handover window, see below), `gapdays`, `direct`, `market`, `inferred`, `roundtrip`, `assetid` and an `item` block (`markethashname`, `wear`, `float`, `defindex`, `paintseed`, `paintindex`). - `direct: true` means the item went straight from one inventory to the other. When it was listed on a marketplace in between, `direct` is `false` and `market` names the leg it travelled through: `name`, `price`, `seenat` and `link` as the marketplace feed supplies it (a deep link on some markets, a listing id on others). - `roundtrip: true` marks a handover that is part of an item leaving the account and coming back. That pattern does not occur in ordinary trading. - `inferred: true` marks a handover reconstructed from a legacy previous-owner field rather than from two independent sightings. - `partners` — the same history rolled up per counterpart, strongest first, with who that account is: `steamid`, `trades`, `received`, `sent`, `direct`, `viamarket`, `roundtrips`, `firsttrade`, `lasttrade` and a `profile` block (`personaname`, `avatar`, `avatarfull`, `timecreated`, `timecreatedat`, `loccountrycode`, `vac`, `tradeban`, `inventoryworthpricesteam`; null when the account is unknown to us). Always the FULL history regardless of the filters below, which apply to `data` only. Capped at the strongest 100 counterparts, with `partnerstotal` giving the real number. - `coverage` — `itemstracked` (items of this account we track), `itemswithtrades` (how many of them ever changed hands) and `truncated` (true when the account has more history than one response covers; page through what you get and treat it as a recent window, not the complete record). 🌐 **How to use:** - Pass `steam_id` (SteamID64). Everything else is optional. - Page with `limit` (default 50, max 200) and `offset`; `total` is the number of rows matching your filters. Narrow with `direction`, `partner`, `from` and `to`, and flip the order with `sort`. - Results are cached per account for several hours, so paging through a history and polling the same account are both cheap. - Credits: 1 per started block of 50 returned rows — a default page costs 1, a full 200-row page costs 4, an empty page costs 1. They count against the same Profile allowance as the other Profile endpoints. ⚠️ **How to read the dates:** - These are inventory sightings, not Steam trade logs. A handover happened somewhere between `senderlastseenat` (last time we saw the item with the giver) and `seenat` (first time we saw it with the receiver) — `gapdays` is the width of that window, not the age of the trade. - An item nobody ever scanned is absent entirely. An empty response means we have seen no handover, not that none happened.

⚡ Fetch Steam Inventory with Pricing & Doppler Phase Detection

Baseurl: https://www.steamwebapi.com/steam/api/inventory?steam_id=760000022222&game=cs2&key=YOUR_API_KEY **Fetch a Steam inventory with live prices, float values, and item metadata — rate-limit free.** Returns either Steam's raw response or an enriched version with prices and metadata (controlled via `parse`). --- **Key features:** - **Live prices** from Steam and 10+ third-party markets. - **Float values & stickers** included by default for CS2. - **Doppler phase detection** — automatically detects the exact phase (Phase 1–4, Ruby, Sapphire, Black Pearl, Emerald) from the item image. The `image` field is replaced with the phase-specific variant image. Use `with_phase_price=1` to also get the exact phase price in `pricereal`. - **Trade URL support** (CS2) — access 7–10 day trade-locked items. Higher failure rate and slower than normal requests — avoid for time-critical applications. If you don't need blocked items, use the normal endpoint without Trade URL. - **Own inventory** — use `steam_login_secure` to fetch your own inventory without the 10-day block. No `steam_id` needed (will be ignored). Find the cookie in your browser dev tools. - **Fallback mode** — returns cached data when inventories are private or unavailable. - **Steam Community URL compatible** — works like `https://steamcommunity.com/inventory/{steamid}/730/2`. Replace the Steam URL with our Baseurl. - **Pagination** — use `limit`, `offset`, and `start_assetid` for large inventories that span multiple Steam responses. - **Multiple formats** — JSON, CSV, XML, gzip, and more.

Parameters

Naam Type Verpl. Beschrijving
key string ja Your API key from the dashboard (top-right corner). Required for authentication.
steam_id string ja The Steam ID of the user. Accepts formats: `steamid`, `steamid3`, `steamid64`, or vanity URL. Using account names may slow the request due to additional Steam API calls.
state string nee Specifies the inventory fetch mode:\n- `active` (default): Fetch live inventory from Steam.\n- `fallback`: Try live first, fallback to cached data if private/inaccessible.\n- `takedb`: Always fetch from our database (fastest, may be outdated).\n\nCached data includes timestamp in response headers.
steam_login_secure string nee Your Steam login cookie for fetching your own inventory WITHOUT the 10-day trade block. When provided, `steam_id` is ignored. Find this cookie in your browser dev tools under "steamLoginSecure".
game string nee Short name of the game. Default is "cs2".
parse string nee Enable steamwebapi parsing for enriched item data with prices and metadata. Set to `0` to get raw Steam response. Default: `1`
language string nee Preferred language for item names and descriptions. Default: `english`
no_cache string nee Bypass the default 3-day cache to get fresh data directly from Steam. Costs +1 additional credit. Default: `0`
group string nee Group identical items by market hash name and sum their count. Useful for inventories with many duplicate items (e.g., cases, keys). Default: `0`
sort string nee Sort items by criterion:\n- **Steam prices**: `price_max`, `price_min`\n- **Real/market prices**: `price_real_max`, `price_real_min`\n- **Mix prices**: `price_mix_max`, `price_mix_min`\n- **Other**: `count`, `name`\n\nDefault: `price_max`
currency string nee Currency for item prices. Only works when `parse=1`. Default: `USD`
select string nee Comma-separated list of fields to include in response. Reduces response size for faster transfers. Example: `markethashname,pricelatest,assetid,float`
with_no_tradable string nee Include non-tradeable items (trade-locked items, StatTrak swap tools, etc.). Default: `0`
trade_url string nee Steam Trade URL. Fetches the partner inventory via the authenticated trade path; for CS2 it automatically includes 7-10 day trade-locked items. Costs +1 credit (ignored when `steam_login_secure` is set). Format: `https://steamcommunity.com/tradeoffer/new/?partner=123456&token=AbCdEf`
offset integer nee Skip the first N items. Use with `limit` for pagination. Default: `0`
limit integer nee Maximum number of items returned by this API. Large Steam inventories may require pagination with `start_assetid`. Default: `10000`
try_first_seven_days_blocked_items string nee CS2 only: Use the trading inventory to also return trade-locked items. `1` = try trading inventory first and fall back to the normal inventory when it yields nothing. `2` = trading inventory only — no fallback, the request fails instead of returning an inventory without the locked items. Increases response time and failure rate. Costs +1 credit. Default: `0`
markets string nee Comma-separated list of markets for price calculation. `pricereal` = lowest price among selected markets. Example: `skinbaron,skinport,dmarket`
with_prices string nee Include detailed market prices array for each item with price, market name, logo, quantity, and direct link. May increase response time. Default: `0`
with_phase_price string nee CS2 Doppler items only. Replaces `pricereal` with the lowest selected-market price for the detected phase (e.g. Phase 2 instead of the generic Doppler price) and `pricerealmedian` with the selected-market median for that phase. Without `markets`, all available third-party markets are used. `pricereal24h`, `pricereal7d`, `pricereal30d`, and `pricereal90d` are set to `null` because these inventory horizon fields are not phase-scoped. Rollout-forward exact phase history is available through `POST /steam/api/items/history`; it does not populate the legacy inventory horizon fields. `winloss` and `winlossprice` are set to `null` because Steam has no phase-specific listing price to compare against. Only applies when a phase is detected AND the phase has a known price. If no phase price exists, all fields stay unchanged. Default: `0`
search string nee Filter items by name (case-insensitive). Matches partial names. Example: `ak-47`
production string nee Set to 1 in production to remove info fields and get faster responses. Will be required in future API versions. Default: `0`
trade_locked string nee Show trade-locked items in your own inventory. Requires `steam_login_secure` parameter. Default: `0`
start_assetid string nee Pagination for inventories that span multiple Steam responses. Check the `last_assetid` response header and use it here for the next page. Repeat while the header is present.
format string nee Response format. Use `gzip` or `zip` for compressed downloads. Default: `json`
pretty string nee Pretty-print JSON output. Only for json/gzip/zip formats. Default: `0`

POST /steam/api/guard/add

🆕 Add / activate authenticator (maFile, both steps)

Generates a Steam mobile authenticator (maFile) — the full lifecycle in ONE endpoint. The step is auto-detected from the parameters (or force it with `step`: 1/2). STEP 1 (add) — send `username` + `password`. If the account uses email Steam Guard, the first call returns HTTP 200 `{ "state": "NEED_EMAIL_CODE", "loginsession": "...", "nextrequest": {...} }`; read the emailed code and call again with `emailcode` + `loginsession`. On success you get the maFile + accesstoken and Steam sends an SMS. STEP 2 (finalize) — send `sharedsecret` + `accesstoken` (both from step 1) + `activationcode` (the code Steam sent, by SMS or email). Alternatively send the whole `mafile` + `activationcode` (sharedsecret/accesstoken are then read from it). `smscode` and `emailcode` are accepted as aliases for `activationcode`. The presence of `sharedsecret`, a `mafile`, or an activation code selects this step. Works with or without a phone number: with a phone Steam sends the activation code by SMS, otherwise by email. Set `mafiledownload` to true (step 1) to receive the maFile as a downloadable `.maFile`. IMPORTANT: store the revocation_code — it cannot be recovered.

Parameters

Geen parameters naast je API-sleutel.

Voorbeeldverzoek

curl -H "X-Api-Key: YOUR_API_KEY" \
  "https://www.steamwebapi.com/steam/api/guard/add"

Responses

  • 200 Add (login): AWAITING_FINALIZATION — the maFile (with fully_enrolled already set to true so the saved file is final-ready), accesstoken, a mafiledownloadlink (a stateless data: URI that downloads the maFile) and mafilefilename (the <steamid>.maFile name to use with an <a download>) — or NEED_EMAIL_CODE (loginsession). Finalize: confirmation that the mobile authenticator is now active. With mafiledownload=true: the maFile as a file attachment.
  • 402 Requires Trade API access — shares the "trade" rate limit.
  • 409 The account already has an authenticator.
  • 422 Validation failed, or the email/activation code was required or rejected.
  • 502 Steam rejected the request.
  • 503 Steam unreachable.
POST /steam/api/guard/remove

🗑️ Remove authenticator

Deactivates the authenticator. Logs in with the current Guard code (from sharedsecret) to obtain an access token, then revokes using the revocationcode. This switches the account back to email Steam Guard.

Parameters

POST /steam/api/trade/history

🔎 Retrieve Trade History

Baseurl: https://www.steamwebapi.com/steam/api/trade/history?key=YOUR_API_KEY 💬 **Retrieve the trade history of a user.** - This endpoint uses the official Steam Web API (IEconService/GetTradeHistory) for accurate and reliable trade data. - Perfect for verifying trade success and tracking the user's trade activity. - **Rate Limiting:** You may experience delays if too many requests are made in a short period, as each `steamloginsecure` token is rate-limited. - **Real-time Data:** The `steamloginsecure` token ensures real-time data retrieval from Steam. You can use the Extension for automatic token retrieval. - **Trade Protection System:** With Steam's Trade Protection System, trades can be reversed within 7 days. The `tradeprotected` and `tradeprotecteduntil` fields indicate if a trade is still in the protection period. The exact settlement date comes directly from Steam. - **New Fields:** Each trade now includes a `tradeid` field and `tradeprotecteduntiltimestamp`. Received items include `originalassetid` and `newassetid`. Sent items include `newassetid`. Items may include `ownerdescriptions` when available from Steam. 🛠️ **Important Parameters:** - **steamloginsecure**: Required. The raw steamLoginSecure token from the `steamcommunity.com` cookie for authentication. - **after_time**: Optional. Pagination cursor — pass the value from `nexthistoryaftertimestamp` of the previous response. - **after_trade**: Optional. Pagination cursor — pass the value from `nexthistoryaftertrade` together with `after_time`. - **assetid**: Optional. Filter trades by a specific asset ID to track a particular item. 🌐 **How to Use:** - Send the `steamloginsecure` cookie value (or use our Extension for automatic retrieval) to fetch trade history data for the user. - Use the `after_time` and `after_trade` parameters together for precise pagination (both values come from `nexthistoryaftertimestamp` and `nexthistoryaftertrade` of the previous response). - Use the `assetid` parameter to track specific items and check if they were involved in reversed trades. Searches across `assetid`, `originalassetid`, and `newassetid`. - Check the `status` field in the response to determine if a trade is "traded" or "reversed". - The `tradereturned` property provides details about reversed trades, allowing services to unfreeze funds after the 7-day trade hold period. - **Note:** `participantusername` contains the trade partner's SteamID64 (username is not available from the Steam API). Use `participantsteamid` for the same value.

Handleidingen

Getting Started

Welcome to SteamWebAPI — a high-quality API service that gives developers seamless access to Steam game data, user profiles, inventories, item prices, and more. No direct Steam API dependency, no IP blocking risk.

SteamWebAPI is an independent service and is not affiliated with Valve, Steam, or any of their partners. All rights belong to their respective owners.

How to Use

Getting started takes three steps:

  1. Make a GET request to any API endpoint.
  2. Browse the endpoints in this reference — pick one from the sidebar.
  3. Send your API key in the recommended X-Api-Key HTTP header.

Authentication

Every production API request requires an API key. Use the header for new integrations:

Recommended HTTP Header

X-Api-Key: YOUR_API_KEY

Legacy Query Parameter

https://www.steamwebapi.com/steam/api/inventory?key=YOUR_API_KEY

The ?key= parameter remains supported for backward compatibility. Avoid query-string credentials in new applications.

How to Get an API Key

  1. Click "Login with Steam" to create an account.
  2. Go to your Dashboard → API Key.

Your Steam data is not stored by SteamWebAPI.

Is it Free?

The free tier provides limited access for initial integration work. Endpoint groups, premium data and limits depend on the selected plan; verify them on the pricing page before deployment.

Resources

Production Use

Use these parameters and best practices to build a stable, resilient integration on top of SteamWebAPI in production environments.

production=1 — Stable Versioning

The production=1 parameter ensures that your integration is not disrupted by unexpected changes introduced in API updates, and allows SteamWebAPI to monitor active production users.

Benefits

  • You receive the exact same response structure already working in your environment.
  • After two weeks, your request automatically upgrades to the new stable version — use this period to test.
  • You have enough time to adapt your integration before migrating to the new version.

Use version=latest to access the newest API response with all current changes even while in production mode.

critical=1 — Real-Time Safety Switch

In addition to production=1, the critical=1 parameter provides an automatic safety mechanism for real-time endpoints such as /inventory or /item.

For the /items endpoint, critical=1 is automatically activated in production mode. For all other endpoints it defaults to 0 but can be manually enabled.

What Does critical=1 Do?

  • The API automatically checks whether a critical issue has been flagged (very rare under normal circumstances).
  • If a critical issue is detected, all requests with critical=1 are temporarily blocked to prevent bad data.
  • You do not need to deactivate your endpoint manually — the system handles it automatically.

When Should You Use critical=1?

Enable it for any operation that depends on real-time data and has financial impact:

  • Skin deposit services (SkinPay, DMarket, BitSkins, etc.)
  • Automated trades via bots
  • Any purchase or trade flow where a wrong price causes a loss

Parameter Summary

Parameter Description
production=1 Use on all production endpoints — guarantees stable response structure.
version=latest Opt in to the latest response format even in production mode.
critical=1 Enables real-time safety switch. Auto-enabled on /items in production.

Best Practices

General

  • Always pass production=1 on every endpoint used in production.
  • Always pass critical=1 for real-time financial operations.
  • Pull /items prices every 30 minutes to 24 hours and cache them locally in your backend.
  • This endpoint is not a backend service — store the data yourself and wrap calls in try-catch.

Item Response Validation (Critical Operations)

Before using an item price in a trade, purchase, or bot decision, always verify two fields:

// ✅ Safe to use
if (item.unstable === false && item.checkedAt !== null) {
    // Price is validated and hasn't spiked > 10% vs. yesterday
    proceed();
}

// ⚠️ Do NOT use if:
// item.unstable === true   → price is flagged as unstable
// item.checkedAt === null  → price has not been validated yet

If checkedAt is null, the price has not yet been validated by the system. Do not use such items in critical operations.

Rate Limits & Subscriptions

  • Rate limits vary by plan — check your Dashboard for current limits.
  • Subscriptions are processed via Stripe — choose between an auto-renewing recurring plan or a one-time, non-renewing plan at checkout.
  • Newly released game items are typically added within 1–3 days.
  • All Pro plans include priority support.

Plans, Limits & Data

Choose an endpoint from the product you are building, then verify that endpoint group's access and limits before deployment.

Use the "What do you want to build?" helper in the sidebar when you are unsure which endpoint fits your project.

Which endpoint group do I need?

What you are building Start with Typical plan family
Inventory valuation or marketplace deposits /steam/api/inventory Inventory
Item catalogue or current Steam prices /steam/api/items Item or balanced
Marketplace comparison /price-api and market endpoints Item or Enterprise
Player profile or account context /steam/api/profile Profile or balanced
CS2 float inspection /steam/api/float Float

Access and request limits

Limits are assigned by endpoint group and plan. The pricing page is the commercial source of truth; your dashboard shows the limits active on your account. Do not assume a free or general limit applies to inventory, profile, history or bulk item endpoints.

Data freshness

Freshness varies by source and product. Read the response timestamp fields and the product page coverage notes instead of assuming one global refresh interval. The public explorer shows current source and update times on a bounded sample.

Common error cases

Status Meaning Action
400 Invalid or missing input Check required parameters and accepted formats.
401 / 403 Authentication or plan access failed Send X-Api-Key and verify endpoint access.
404 Requested resource was not found Verify the identifier and supported game.
429 A rate limit was reached Honor Retry-After or select a suitable plan.
5xx Temporary service or upstream failure Retry idempotent calls with bounded backoff.

Production and Enterprise

For higher volume, custom marketplaces, custom data structures, scheduled delivery or contractually agreed support, use the Enterprise path. Operational and business verification is available in the Trust Center.

Steam Trading API

The Steam Trading API offers a robust solution for facilitating game item trading without the need for a traditional Steam Trading Bot. Build platforms like Skinport, Skinbaron, or DMarket — or create your own instant skin buy/sell service.

You won't need a Node.js trade bot — our Tradeoffer API supports your marketplace, trading site, or any other innovative concept you have in mind.

Trade API Features

Feature Description
Create a Tradeoffer Generate trade offers for any desired item.
Accept a Tradeoffer Accept trade offers for any item you choose.
Cancel / Decline Cancel or decline trade offers as needed.
Tradeoffer Status Confirm and monitor trade statuses in real time.

What Can You Build?

B2C vs. P2P Trading Models

B2C (Business-to-Customer)

In a B2C model your bot directly interacts with customers — similar to how Skinport, Skinbaron, and DMarket operate. You own an account where items are sent or received instantly without delay.

Challenge Difficulty
Retrieving the steamloginsecure cookie Low
Mobile confirmation when sending skins Low

P2P (Peer-to-Peer)

In a P2P model customers send items directly to the buyer. Platforms like Whitemarket, Waxpeer, or Buff use this approach — items reach the owner directly and are released by the seller after a delay.

SteamAuth — The Modern Approach

steamauth.app is a browser extension that lets your users share their Steam login cookie securely with your platform — no bot needed.

Many major marketplaces already use SteamAuth. With it your customers only need to install the extension — you can then retrieve inventory, trade status, and execute trade actions without any additional programming on the user's side.

P2P with SteamAuth (Recommended)

  • Your users install the SteamAuth browser extension (Chrome, Opera, Firefox).
  • You can then retrieve their steamloginsecure cookie via the extension.
  • Use our Trade API endpoints to create, accept, or cancel offers on their behalf.
  • No need for a traditional trade bot or manual cookie handling.

P2P without SteamAuth (Advanced)

Alternatively, you can build your own extension or solution and use our API endpoints with a steamloginsecure cookie that you obtain yourself.

SteamAuth Features

Feature Description
Inventory Data Access and share CS2 inventory securely with trusted websites.
Trade History View and analyze complete trading history.
Create Trades Initiate trades directly through connected websites.
Pending Trades Monitor all outgoing trade offers in one place.
Incoming Trades Review and respond to incoming trade offers.

Available for

  • Chrome
  • Opera
  • Firefox

Security & Authentication

All trade endpoints require a JSON payload and a valid steamloginsecure cookie obtained either via SteamAuth or manually from steamcommunity.com.

While our API can perform various trade actions, Steam still requires mobile confirmation for certain actions. We are actively exploring solutions for automated mobile confirmation and plan to provide an open-source solution in the future.

Quick Start

  1. Get your API key from the Dashboard.
  2. Have your users install SteamAuth (for P2P).
  3. Use the POST /steam/api/trade/create endpoint to create trade offers.
  4. Monitor status via the trade status endpoint.
