About CoinGecko

CoinGecko API provides cryptocurrency market data through a REST API, WebSocket, webhook, SDKs (TypeScript and Python), a CLI tool, a spreadsheet add-on, and an MCP server for AI agent integration. It covers real-time and historical prices, market capitalization, trading volume, OHLC/OHLCV candlestick data, onchain DEX data, exchange and derivatives data, NFT collection data, coin categories, public treasury holdings, and global market statistics. Data spans over 43 million tokens, more than 1,900 exchanges, and 250+ blockchain networks, with up to 12 years of historical data.

Prices are aggregated from centralized and decentralized exchanges using CoinGecko's Bitcoin Price Index as a reference benchmark, with outlier filtering applied. The company has operated since 2014 and reports a 99.9% uptime SLA; the API is SOC 2 Type 2 compliant and independently audited.

The API is aimed at developers building exchanges, wallets, trading and custody interfaces, AI agents and DeFAI applications, analytics and portfolio tracking tools, institutional trading infrastructure, DeFi and Web3 applications, and audit/compliance reporting systems. Customers referenced include Coinbase, MetaMask, Phantom, Chainlink, Kraken, 0x, and Deblock. A free tier is available with no credit card required, alongside enterprise and sales-contact options.
