What it does
The CoinGecko API gives prices, market capitalisation, volume and price history for thousands of cryptocurrencies, plus data on exchanges, categories, trending coins and NFTs. It is widely used for crypto price widgets, portfolio trackers and charts. Responses are JSON. The free Demo plan needs a free API key and has a monthly call limit; paid plans offer more calls and data. An official MCP server at https://mcp.api.coingecko.com/mcp lets AI agents use the API without a key.
