About
CoinMarketCap API is a cryptocurrency and DEX market data API that exposes REST endpoints for listings, quotes, historical data, exchange data, global metrics, trending data, content data, and index values. The service also includes an MCP endpoint and x402 pay-per-request access for selected routes.
The free offering includes a keyless public API with no account or API key required for selected endpoints, plus a Basic plan with a free authenticated key. The Basic plan includes 15,000 monthly call credits, 50 requests per minute, 11 data endpoints and exchange asset reserve endpoints, personal use, and 1 API key. The pricing page also states that most endpoints update every 1 minute.

Free Tier Value
This free tier is a capped but genuinely usable starter plan: it includes 15,000 monthly API credits, basic support, and a small authenticated key allowance with a 50 RPM limit. Compared with the cheapest paid Builder plan at $29/month and 150K credits, it delivers about 10% of the paid credit volume plus a narrower endpoint set, so a fair value estimate is about $15/month. A credit card is not required to try the public API, and the offer is perpetual rather than time-limited, which supports a meaningful free-tier score.
