# 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: **16 years** of historical data, **50 million+** tracked assets, **941+** exchanges, **90+** endpoints, and about **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. ## What data is available - **Market data**: Live cryptocurrency prices, market cap, volume, listings, quotes, and historical OHLCV data. - **Exchange data**: Exchange metadata, rankings, market pairs, volume data, and proof-of-reserves assets. - **DEX data**: On-chain token, pair, liquidity, platform, and OHLCV data across decentralized ecosystems. - **Market intelligence**: Global market metrics, Fear and Greed, content, community trends, and broader market signals. ## Common use cases - Build live price widgets, watchlists, and portfolio dashboards - Power ranked market views, screeners, and discovery experiences - Fetch historical data for charts, analytics, and backtesting - Monitor exchange activity, market pairs, and liquidity - Add DEX token, pair, and on-chain market data to your product - Combine market data with headlines, trends, and community signals ## Start here 1. **Try it instantly - no key** Call a curated set of endpoints with zero setup using the [Keyless Public API](https://coinmarketcap.com/api/documentation/pro-api-reference/keyless-public-api).
