CS2 Market Data API for bots and traders

Get BUFF-compatible enterprise market snapshots — lowest listings, float ranges, and liquidity ranks — from a dedicated cache on buff-api.masterspanel.com. Your trading bots never need a live Buff session for these reads.

Built as a Master Panel add-on: pay with panel balance, mint an API key, and pull JSON with standard Bearer auth, ETags, and rate-limit headers.

Master Panel is not affiliated with BUFF. Endpoints are BUFF-compatible replicas for subscribers. Trading, buy/sell, and account APIs are not included.

Who it is for

  • Float items — float range data for items (GET /v1/buff/enterprise/float/items).
  • Liquidity rank — liquidity ranking snapshot (GET /v1/buff/enterprise/items/liquidity-rank).

Limits and reliability

The API is cache-and-forward: we ingest Buff enterprise snapshots on a fixed schedule and serve them from Redis/origin cache. That keeps latency predictable and protects upstream credentials. Fair-use quotas apply (requests per minute/day, concurrency, and monthly bytes). When limited, you receive HTTP 429 with a clear reason code.
