Crypto Exchange APIs
Crypto exchange APIs come straight from a trading venue, with its own tickers, order books, trades and candles, and usually signed endpoints for placing orders. Public market data needs no key on Coinbase, Bitfinex and MEXC. Several are regional: Indodax prices in rupiah, Mercado Bitcoin serves Brazil and VALR South Africa. CoinAPI and 0xArchive unify data across venues instead.

Choosing a Crypto Exchange API
Is there a free Crypto Exchange API?
Yes. Coinbase Exchange, Binance, KuCoin, Bitfinex, BitMEX and 9 others are free to use, and 0xArchive and CoinAPI have a free tier alongside paid plans.
Which Crypto Exchange APIs work without an API key?
Coinbase Exchange, Bitfinex, dYdX, Indodax, MercadoBitcoin and 1 other need no key or sign-up, so you can try them with a plain request.
Can I call a Crypto Exchange API from front-end JavaScript?
Coinbase Exchange, dYdX and MercadoBitcoin 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 Exchange APIs in a commercial project?
0xArchive permits commercial use. CoinDCX restricts it, for example to non-commercial or attributed use, so read the terms first.
Which Crypto Exchange APIs work with AI agents?
0xArchive has an MCP server, so an AI agent can call it directly. Coinbase Exchange, BitMEX and MercadoBitcoin publish an OpenAPI spec for generating clients and tools.
