Why list with SteamWebAPI?

A single integration plugs your prices into the entire skin-trading data layer — every endpoint, every partner site, every aggregator.

Reach every buyer in the ecosystem

Our pricing data feeds hundreds of comparison sites, Discord bots, trading tools and inventory valuation apps. One integration, distribution across the entire skin-trading ecosystem.

Your own SEO landing page

Every listed marketplace gets a dedicated /{your-slug}-api landing page on a high-authority domain — long-form content, structured data, and durable organic traffic that keeps working for you.

Deep links with attribution

Per-item deep links carry your tracking parameters, so every click that converts on your side is traceable back to SteamWebAPI traffic. Real, measurable acquisition.

High buyer-intent traffic

Users hitting our price endpoints are deep in the purchase funnel — they want a price and they want to buy. That intent converts far better than generic ad traffic or top-of-funnel discovery.

Permanent navbar presence

Listed marketplaces appear in our global Markets dropdown — passive, 24/7 exposure to every visitor on the platform without any extra effort on your side.

Verified Partner badge (opt-in)

Turn on an optional Verified Partner badge across our pricing pages — a trust signal for buyers in a space where trust is hard to earn. Off by default, on with a single toggle whenever it helps your conversion.

Included automatically

You're not just paying for views — you're paying for placement

Every site, bot and tool that consumes SteamWebAPI pricing data renders your marketplace name in its UI alongside the price. The moment you integrate, your brand starts showing up across the entire skin-trading ecosystem — without you having to negotiate a single partnership.

Price-comparison websites

Skin price aggregators and comparison tools pull our data and render your name next to your price in their UI.

Browser extensions

Steam-overlay extensions that show third-party prices on the Community Market list your marketplace alongside competitors.

Discord trading bots

Community bots that quote prices in trading servers cite your marketplace as a source — thousands of impressions in chat per day.

Inventory valuation tools

Sites that value Steam inventories use our pricing — when a user inspects their own items, your buy-price is visible item by item.

Trading & arbitrage dashboards

Power users running cross-market arbitrage dashboards see your marketplace listed in the spread analysis next to every item.

Affiliate & content sites

Niche skin-trading blogs, YouTube content creators and Twitch streamers use our endpoints — your name surfaces in their recommendations.

The placement is automatic. Once you're in our pipeline, every downstream consumer that renders prices renders your name with them. No outreach, no per-partner integration, no ad budget — pure brand distribution as a side effect of being listed.

From inquiry to live in days

No long contracts, no integration headaches. Once your API is ready, we handle the rest of the pipeline.

Apply

Send us your marketplace details — name, domain, games you cover, and a sample API response. We review for fit and reputation.

2

API review & QA

We validate your endpoint against a real-world sample set, check response time and stability, and confirm the data quality.

Invoice & payment via Stripe

4

Go live in 24–48h

Your marketplace appears in our pricing pipeline, comparison endpoints, navbar dropdown and gets a dedicated SEO landing page. From month 3 you receive a €300 invoice each month.

API requirements

A single JSON endpoint returning a flat array of items — name, available quantity and minimum price. Three fields. Most marketplaces ship this in a few hours.

Response fields

Field Type Required
market_hash_name string required
quantity integer required
min_price integer (cents) required
  • Response is a flat JSON array — no wrapper object, no pagination required.
  • min_price is an integer in minor units — e.g. 95 means €0.95. Base currency is agreed at onboarding (EUR or USD).
  • Auth optional: none, API key in header, or Bearer token.
  • Multi-game endpoints supported (CS2, Dota 2, Rust, TF2, others).
  • A per-item deep-link URL template can be supplied separately at onboarding for attribution.
Sample request curl
curl -s \
-H "Accept: application/json" \
-H "Authorization: Bearer YOUR_TOKEN" \

How billing works: The first invoice is €600 and covers the one-time integration fee plus your first 2 months of API access. From month 3 onwards, we issue a €300 invoice each month. All invoices are issued through Stripe and settled by card, SEPA or wire. Unpaid invoices result in deactivation of the listing until payment clears.

What we expect

  • API uptime above 99% — we pause listings that fail repeatedly.
  • Honest pricing — quoted prices must be the prices a buyer actually pays.
  • Stable response shape — schema changes communicated in advance.
  • Reasonable rate limits — at minimum a few requests per minute from our pipeline.
  • Stripe invoices paid on time — unpaid invoices trigger automatic deactivation.
  • A real contact for the integration relationship.

What we don't list

  • Marketplaces with a public history of fraud, scams or chargebacks.
  • Platforms knowingly selling stolen or duplicated inventory.
  • Endpoints returning consistently misleading prices (dumping, bait listings).
  • Operators that refuse a basic compliance / KYC contact check.

Curation protects every honest marketplace on the platform — and the value of being listed.

Frequently asked questions

Everything marketplaces typically ask before signing up. Missing something? Mention it in your application email.

How does the pricing work exactly?

Your first invoice is €600 and covers the one-time integration fee plus your first 2 months of API access. From month 3 onwards we issue a €300 invoice each month. There is no minimum term beyond the first €600.

Is there a minimum contract length?

No. The integration runs month to month and you can cancel at any time. The only upfront commitment is the €600 first invoice — which already buys you the integration plus two full months of API access.

How do I pay?

After the API review we issue a Stripe invoice. You can pay by credit/debit card, SEPA direct debit, ACH or international wire. We do not store card details — Stripe handles all payment data.

What happens if I do not pay an invoice?

Unpaid invoices result in automatic deactivation of your listing across the SteamWebAPI pipeline until the invoice is settled. We send reminders before deactivation and reactivate within a few hours of payment.

What exactly do you need from my API?

A single JSON endpoint returning a flat array of items with three fields per item: market_hash_name (string), quantity (integer), and min_price (integer in minor units / cents). That is the entire required contract.

How long does the full onboarding take?

Once your API is ready, the integration usually goes live within 24-48 hours after the first invoice is paid. The longest part is normally on your side: getting the API endpoint built and stable.

Can my API cover multiple games (CS2, Dota 2, Rust, ...)?

Yes. Multi-game endpoints are fully supported — either via a query parameter or separate endpoints per game. We will agree the exact contract during the API review.

What kind of authentication can I require?

Anything reasonable: no auth, an API key in a custom header, or a Bearer token. We will hold the credential securely on our side and only use it for the integration pipeline.

How often do you poll my endpoint?

Polling frequency depends on your inventory size and your stated rate limit. We will agree the cadence during onboarding — typically every few minutes for the lowest-price endpoint.

Can I pause the listing if I need to?

Yes. You can pause and resume your integration without paying the integration fee again, as long as the pause is shorter than 12 months. Tell us and we will park the listing and stop billing until you are ready.

Is the Verified Partner badge automatic?

No, it is opt-in. By default no badge is shown. You can turn the Verified Partner badge on or off at any time once your integration is active.

Do you provide click attribution / referral tracking?

Yes. You can supply a URL template with your own tracking parameters (UTM, custom referral IDs, sub-IDs) and we will use it for every deep link to your marketplace.
