Fixer

Fixer is a lightweight and developer-friendly API service designed to provide real-time and historical foreign exchange rate data for a wide range of global currencies. It aggregates financial data from multiple sources, including institutions like the European Central Bank, to deliver accurate and frequently updated exchange rates. The API supports over 170 currencies and offers multiple endpoints that allow developers to retrieve latest rates, perform currency conversions, and analyze historical trends over time. One of its key strengths is its simplicity, as it uses straightforward RESTful endpoints and JSON responses that can be easily integrated into web or mobile applications. Fixer also supports time-series and fluctuation data, enabling more advanced financial analysis and forecasting use cases. While a free tier is available with some limitations, more advanced features such as higher request limits and additional base currencies are offered through paid plans.
