How the CurrencyFreaks API Works

CurrencyFreaks is a free currency exchange rate API that gives developers access to real-time and historical forex data through a simple REST API. Send a request to our endpoint with your API key and the currencies you need — you get back clean JSON or XML with mid-market rates, ready to use in any application.

The free plan includes 1,000 API calls per month with no credit card required.
