Dedicated Buff163 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/buff/prices

Live prices snapshot

Returns the current Buff163 catalogue as a flat array. Each row is one item with the lowest active price we have on record.

  }
]
  • · 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/buff/history

Per-item price history

Daily-snapshot history of the lowest Buff163 price for a given item, ideal for charts and portfolio trackers.

Sample response
[
  {
    "createdat": "2026-09-03T00:00:00+00:00",
    "price": 124.40,
    "quantity": 1
  },
  {
    "createdat": "2026-09-09T00:00:00+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 Buff163

Buff163 (often written just "Buff") is operated by NetEase and is by a wide margin the largest CS2 marketplace in Asia by both listing count and 24-hour trade volume. Prices there typically sit a few percent below Western marketplaces, which makes Buff data essential for any serious price comparison, arbitrage tool or inventory valuation engine.

Scraping Buff yourself is painful: aggressive Cloudflare rules, geo-restrictions, and a request budget that runs out fast. Our API does that work for you and normalises every Buff listing into the same JSON schema we use for Skinport, CSFloat, DMarket and the rest of our markets — so you only ever write one integration.

You can filter by game (CS2 and Dota 2 are the biggest coverage areas on Buff), by item name, by price range and by float. Responses include market hash name, real and listed prices, recent sale counts, and a side-by-side view of every other marketplace tracking the same item.

Buff163 API — FAQ

What is Buff163?

Buff163 is the largest Chinese community marketplace for Steam game items, primarily CS2 and Dota 2. It launched in 2017, runs on RMB pricing, and consistently shows higher listing counts than every Western marketplace combined.

Which games does the Buff API cover?

Through our API we focus on CS2 and Dota 2, the two largest categories on Buff163. Coverage for smaller games depends on which scrapers we run — check the 'Supported games' section above for the current list.

How do I access Buff163 prices?

Get an API key from the dashboard and call /steam/api/items with markets=buff. The response is the same DTO we use for every other marketplace — one schema, one integration.

How fresh are Buff prices via the API?

We scrape Buff on a tight schedule and the 'Last refresh' stat above shows the most recent successful pull. Highly liquid items refresh more aggressively than long-tail listings.

Is Buff163 safe to use?

Buff163 has been operating since 2017 and is the de-facto standard for skin trading in mainland China. Always verify directly with the marketplace before transacting — we surface Buff for data purposes, not as a trading recommendation.
