Exchange-RateAPI fetches live mid-market rates on every request rather than serving a once-a-day snapshot, so you always get current pricing. Rates come from Reuters and interbank feeds, cover 160+ currencies with any base currency, and are delivered with very low latency from Cloudflare's global edge network. It pairs institutional-grade data with a developer-friendly REST API, official SDKs, and a genuinely usable free tier.
Many currency APIs update only once or twice a day, lock real-time data behind expensive tiers, or are awkward to integrate. Exchange-RateAPI gives real-time mid-market rates (no retail markup), simple bearer-token auth, CORS support, and clean JSON responses, plus official SDKs for JavaScript/TypeScript, Python, and PHP. Pricing is transparent and affordable — a perpetual free tier with no credit card, and paid plans from €4.99/month — backed by low-latency edge delivery.
Developers and product teams who need reliable foreign-exchange data: fintech and payment apps, SaaS platforms, e-commerce checkout and pricing, invoicing and accounting tools, travel and booking products, and any global application that displays prices or converts currencies. It suits both solo developers starting on the free tier and businesses scaling to high request volumes.
Exchange-RateAPI was built by developers frustrated with exchange-rate APIs that refreshed only once a day, charged heavily for real-time access, or were awkward to integrate. By building on modern edge infrastructure, the team set out to offer accurate, real-time mid-market rates that are fast, simple to integrate, and affordable enough to start for free — making institutional-grade FX data accessible to any developer.
Exchange-RateAPI runs on Cloudflare Workers (serverless edge compute) with Workers KV for storage, written in TypeScript. It exposes a REST/JSON API with official SDKs for JavaScript/TypeScript, Python, and PHP. Exchange-rate data is sourced from Reuters and interbank feeds. Billing is handled via Stripe and transactional email via Resend.
