Market Data APIs
Crypto market data comes from two kinds of source. Aggregators such as CoinGecko, CoinMarketCap and Coinpaprika combine prices, market caps and history across many exchanges. Exchange APIs like Coinbase, Bitfinex and MEXC publish their own tickers and order books, often without a key. Specialist feeds add derivatives funding rates, whale trades or treasury holdings from SEC filings.

Choosing a Market Data API
Is there a free Market Data API?
Yes. Alpha (Mossland), Binance, Bitfinex, BitMEX, Bybit API and 14 others are free to use, and CoinGecko, CoinMarketCap, Coinpaprika, ByKaranteli, Codex and 10 others have a free tier alongside paid plans.
Which Market Data APIs work without an API key?
Coinpaprika, Alpha (Mossland), Bitfinex, Coinbase Exchange, Coinlore and 5 others need no key or sign-up, so you can try them with a plain request.
Can I call a Market Data API from front-end JavaScript?
Coinpaprika, Alpha (Mossland), Coinbase Exchange, Coinlore, FraudCoins and 2 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 Market Data APIs in a commercial project?
CoinGecko, CoinMarketCap, CoinLobster, FraudCoins and Sharpe API permit commercial use. ByKaranteli, CoinDCX, Coinlayer, CoinNudge and CorpStacking restrict it, for example to non-commercial or attributed use, so read the terms first.
Which Market Data APIs work with AI agents?
ByKaranteli and CoinLobster have both an MCP server and an OpenAPI spec. CoinMarketCap, Coinpaprika and Alpha (Mossland) have an MCP server, so an AI agent can call them directly. CoinGecko, BitMEX, Coinbase Exchange, CoinCap, MercadoBitcoin and 2 others publish an OpenAPI spec for generating clients and tools.
