Fixer.io started out as a simple, lightweight Open-Source API for current and historical foreign exchange (Forex) rates published by the European Central Bank. After six years of constant growth the Fixer API was taken over by apilayer to join its powerful API suite used by millions of developers and companies arond the world. In the course of this transition, Fixer.io was rebuilt completely and extended dramatically in data richness, exchange rate data accuracy and functionality.
The Fixer API is capable of delivering real-time forex data via API at an accuracy of 6 decimal points and a frequency as high as every 60 seconds. Fixer is built on top of a powerful back-end infrastructure allowing for high availability and response times below 50ms for specific API requests. Capabilities include delivering exchange rates for 170 world currencies, converting single currencies, returning Time-Series data and fluctuation data.
