Forex APIs
Forex APIs serve two audiences: traders who need market data and apps that need reference rates. Finnhub, Twelve Data and Finage provide real-time forex alongside stocks and crypto, while the ECB Data Portal publishes official euro reference rates with policy rates and bond yields, free and keyless. FXNewsBias takes another angle, scoring news sentiment for major currencies.

Choosing a Forex API
Is there a free Forex API?
Yes. ECB Data Portal API is free to use, and Twelve Data, Finnhub, Alpha Vantage, CurrencyBeacon, EOD Historical Data and 6 others have a free tier alongside paid plans.
Which Forex APIs work without an API key?
ECB Data Portal API needs no key or sign-up, so you can try it with a plain request.
Can I call a Forex API from front-end JavaScript?
ECB Data Portal API allows cross-origin requests and needs no key, so it works straight from the browser. For the others, call them from your server so your key stays private.
Can I use Forex APIs in a commercial project?
ECB Data Portal API, CurrencyBeacon and FxFeed.io permit commercial use. Twelve Data, Alpha Vantage, EOD Historical Data, Exchangerate.dev, Finage and 3 others restrict it, for example to non-commercial or attributed use, so read the terms first.
Which Forex APIs work with AI agents?
Twelve Data and Exchangerate.dev have an MCP server, so an AI agent can call them directly. FxFeed.io and FXNewsBias publish an OpenAPI spec for generating clients and tools.
