CoinGecko
CoinGecko is a cryptocurrency data aggregator providing market data, analytics, and information on thousands of crypto assets, exchanges, derivatives, NFTs, and on-chain decentralized markets worldwide. The CoinGecko Developer Platform exposes three primary APIs: the public Crypto Market Data API (Demo plan and free tier), the commercial Pro API for higher rate limits and exclusive endpoints, and the Onchain DEX API powered by GeckoTerminal for decentralized exchange data across 250+ networks. Authentication uses x-cg-demo-api-key (Demo) or x-cg-pro-api-key (Pro) headers, with rate limits ranging from 30 calls per minute on Demo to 1,000 calls per minute on top Pro tiers.
CoinGecko publishes 22 APIs on the APIs.io network, including Asset Platforms API, Categories API, Coins API, and 19 more. Tagged areas include Aggregator, Blockchain, Cryptocurrency, Decentralized Exchanges, and DeFi.
