ExchangeRate-API is a reliable, easy-to-use REST API providing real-time and historical exchange rates for over 165 currencies, built for developers, e-commerce platforms, SaaS apps, and businesses needing accurate currency conversion data.

🚀 Overview

ExchangeRate-API offers accurate JSON-formatted exchange rates via simple HTTPS GET requests, supporting 165+ currencies across 200 countries. Since its launch in 2010 by AYR Tech (Pty) Ltd., it has achieved over 99.99% uptime, served billions of requests, and earned trust from 100,000+ developers and thousands of businesses.

What problem does this project solve? It addresses the unreliability of free currency data sources and the complexity of enterprise FX APIs by providing stable, accurate rates with long-term support—no breaking changes for 15+ years.

Who is it built for? Developers integrating currency features into web/mobile apps, e-commerce stores displaying local prices, SaaS dashboards tracking revenue, and spreadsheet users automating conversions.

Why did you build it? Created to deliver a dependable, developer-friendly service after spotting the gap in consistent, easy-access exchange rate data that apps could rely on without constant rework.
