Query Youpin via our API

Filter the unified /steam/api/items endpoint with markets=youpin to return only Youpin listings — or omit it for a side-by-side view across every marketplace.

→ Single auth header, same JSON schema for every market.
→ Filter by game, item name, price range, float.
→ Sort by price, listing volume, or recency.
→ Same DTO across REST and WebSocket streams.

Youpin API Request

# curl with API key

curl "https://www.steamwebapi.com/steam/api/items?key=$KEY&markets=youpin&game=cs2"

# PHP

$res = file_get_contents('https://www.steamwebapi.com/steam/api/items?key=' . $KEY . '&markets=youpin');

$items = json_decode($res, true);

# Node.js / JavaScript

const r = await fetch(`https://www.steamwebapi.com/steam/api/items?key=${KEY}&markets=youpin`);

const items = await r.json();

Dedicated Youpin endpoints

On top of the unified /steam/api/items route, every market we cover gets two convenience endpoints — one schema, one auth header, every marketplace.

GET /market/youpin/prices

Live prices snapshot

Returns the current Youpin catalogue as a flat array. Each row is one item with the lowest active price we have on record.

Sample response

[
  {
    "market_hash_name": "Souvenir UMP-45 | Gunsmoke (Minimal Wear)",
    "price": 130.69,
    "quantity": 1,
    "createdat": "2026-05-25T00:00:00+00:00",
    "variants": null
  },
  {
    "market_hash_name": "Sticker | Slab (Foil) | Krakow 2017",
    "price": 114.65,
    "quantity": 1,
    "createdat": "2026-05-25T00:00:00+00:00",
    "variants": null
  }
]

· Same JSON schema across every marketplace we cover.
· We surface the lowest price per item — never an average, never a stale tick.
· Optionally filter by market_hash_name or convert prices via ?currency=EUR.

GET /market/youpin/history

Per-item price history

Daily-snapshot history of the lowest Youpin price for a given item, ideal for charts and portfolio trackers.

Sample response

[
  {
    "createdat": "2026-05-18T00:00:00+00:00",
    "price": 124.40,
    "quantity": 1
  },
  {
    "createdat": "2026-05-24T00:00:00+00:00",
    "price": 130.69,
    "quantity": 1
  }
]

· One row per day, always the lowest price we recorded for that day.
· Bounded with start_date and end_date (YYYY-MM-DD).
· market_hash_name is required — history is per-item, not per-market.

Prefer one call across every marketplace? Use the unified /steam/api/items endpoint with markets=… — same DTO, comparison data included.

About Youpin

Youpin898 (sometimes just "Youpin", "U898", or "Yyyp") is the second-largest Chinese marketplace for CS2 items, sitting behind Buff163 in volume but ahead of nearly every Western competitor. Pricing on Youpin frequently differs from Buff by a few percent — making it the second essential data source for any arbitrage or portfolio tool that takes the Chinese market seriously.

Scraping Youpin directly is just as painful as scraping Buff — geo-restrictions, rate limits, anti-bot. Our API does that work for you and outputs the same JSON schema as Buff, Skinport, CSFloat and the others.
