FXRatesAPI

FXRatesAPI is a foreign exchange rates REST API that delivers real-time and historical currency exchange rates for 185+ fiat currencies plus major cryptocurrencies and precious metals. It exposes JSON endpoints for the latest rates, historical rates for any past date, time-series ranges, currency conversion, and a currencies list. A limited tier is usable without an API key; higher request quotas, more frequent updates, and additional base-currency switching are unlocked with a paid API key passed via the api_key query parameter or an Authorization Bearer header.

FXRatesAPI publishes 5 APIs on the APIs.io network, including Convert API, Currencies API, Historical Rates API, and 2 more. Tagged areas include Foreign Exchange, FX, Currency, Exchange Rates, and Forex.

FXRatesAPI’s developer surface includes authentication, documentation, and 6 more developer resources.
