The CS2 market data API: endpoints, data model and markets

CSPriceAPI is a CS2 skin price API covering 13 marketplaces, with 50,000+ items and ~5 min live snapshots. 1+ years of price history.

CSPriceAPI covers both: live BUFF163 and YouPin listing prices in CNY, refreshed about every 5 minutes, alongside 11 other marketplaces such as Skinport, CSFloat and Steam. Buy orders and float-ranged prices for YouPin and BUFF163, and per-phase Doppler prices, come through the same REST API and schema, so Chinese and Western prices can be compared directly.

Every request sends your API key in the x-api-key HTTP header; there is no OAuth flow and no bearer token. Keys are created in the dashboard right after checkout, or as a free 2-day test key in the Discord, and can be rotated in the dashboard. Each key is limited to 10 requests/second.

A CS2 price API delivers live Counter-Strike 2 skin prices and related market data (buy orders, float ranges, volumes, Doppler phases) as JSON over HTTPS. CSPriceAPI aggregates major third-party marketplaces in one REST interface.

Yes. Endpoints include GET /v1/prices/latest for live prices on every listing market, GET /v1/steam for Steam prices and the order book, GET /v1/prices/youpin/buyorder and GET /v1/prices/buff163/buyorder for buy orders, and GET /v2/prices/float-ranged (YouPin) and GET /v1/prices/buff163/float-ranged (BUFF163) for prices per float range. Authentication uses an API key in the x-api-key header.

Yes. CSPriceAPI tracks every Doppler / Gamma Doppler phase individually — Phase 1‑4, Ruby, Sapphire, Black Pearl, Emerald — on every covered marketplace. The phase price is returned alongside the standard listing, not averaged into one value.

No, there is no permanent free API tier. A free 2-day test key can be created instantly in the #get-testkey channel on the Discord: it covers every endpoint except price history, with sales data limited to the last 24 hours. The MCP server has a no-key preview for trying it out: item search plus 5 single-item price lookups per day per IP, from a snapshot up to 6 hours old. Plans start at $50/month; see the pricing page for what each plan includes.
