CoinMarketCap API Overview

The CoinMarketCap API is built for teams that want the most trusted and comprehensive cryptocurrency market data in the industry. As the industry authority and the world’s number one cryptocurrency market data API, it gives developers access to real-time and historical market data, exchange data, global metrics, and DEX data through a single REST API.

Trusted by everyone from individual developers to major finance and crypto institutions, the API combines broad coverage with production-ready scale: 14 years of historical data, 2.4 million+ tracked assets, 790+ exchanges, 40+ endpoints, and more than 1 billion API calls per month. Whether you are building a wallet, exchange, portfolio tracker, analytics platform, trading system, AI product, or research workflow, CoinMarketCap provides the depth and reliability needed to power serious crypto applications.

The platform is designed to scale with your product, from free experimentation to enterprise deployment. Developers can start with a free plan, while commercial and professional tiers unlock higher call limits, broader endpoint access, longer historical coverage, and enterprise-grade licensing. Most plans offer data refreshed every 1 minute, making it well suited for live experiences, market intelligence, and high-frequency crypto products.
