Crypto APIs
Crypto APIs span market data, blockchain data and nodes, DeFi and DEX analytics, and payment gateways. Aggregators like CoinGecko and CoinMarketCap price thousands of coins, while exchanges such as Coinbase publish their own order books, with public data often available without a key. On-chain tools like Etherscan and node providers such as Infura serve raw chain data, and gateways like NOWPayments let you accept crypto.

Choosing a Crypto API
Is there a free Crypto API?
Yes. Coinbase Exchange, Alpha (Mossland), Binance, Bitcoin Halving, Bitfinex and 29 others are free to use, and CoinGecko, Etherscan, 0xArchive, 1inch, Alchemy NFT API and 30 others have a free tier alongside paid plans.
Which Crypto APIs work without an API key?
Coinbase Exchange, Alpha (Mossland), Bitcoin Halving, Bitfinex, Blockchain.com Data API and 25 others need no key or sign-up, so you can try them with a plain request.
Can I call a Crypto API from front-end JavaScript?
Coinbase Exchange, Alpha (Mossland), Bitcoin Halving, Blockscout, BTCGlobe and 17 others allow cross-origin requests and need no key, so they work straight from the browser. For the others, call them from your server so your key stays private.
Can I use Crypto APIs in a commercial project?
CoinGecko, 0xArchive, 1inch, Alchemy NFT API, Bitcoin Halving and 23 others permit commercial use. Etherscan, ByKaranteli, CoinDCX, Coinlayer, CoinNudge and 2 others restrict it, for example to non-commercial or attributed use, so read the terms first.
Which Crypto APIs work with AI agents?
ByKaranteli, ClearTrace, CoinLobster and Ophis have both an MCP server and an OpenAPI spec. Etherscan, 0xArchive, 1inch, Alpha (Mossland), Bitquery and 4 others have an MCP server, so an AI agent can call them directly. CoinGecko, Coinbase Exchange, BitMEX, BlockBee, Blockchain.com Data API and 11 others publish an OpenAPI spec for generating clients and tools.
