CS2Cap API: Build on Normalized CS2 Market Data

CS2Cap is a REST API that aggregates and normalizes market data from 40 CS2 marketplaces — including BUFF163, CSFloat, GameBoost, Skinport, Steam, and more. Whether you’re building a trading bot, pricing dashboard, arbitrage scanner, or portfolio tracker, CS2Cap eliminates the work of integrating each marketplace individually and delivers consistent, structured data through a single base URL: https://api.cs2c.app/v1.

Tiers

CS2Cap offers four tiers. All tiers use the same endpoints and authentication model — tier determines your rate limits, monthly quota, and which endpoints are accessible.

Tier	Requests/min	Requests/month	Notes
Free	20	1,000	Prices endpoint only
Starter	40	50,000	Prices, bids, and 100-item batch lookups
Pro	100	500,000	Prices, bids, sales, portfolio
Quant	300	1,000,000	All endpoints including analytics

Starter includes current prices and bids for known item sets. Sales, raw history, market analytics, listing URLs, and NDJSON snapshots require Pro or Quant where applicable.
