exchangerate.dev is a free foreign-exchange rates API built for developers who need reliable rates without signup friction. The free tier includes 10,000 calls/month with no credit card required, live rates for major currency pairs updating roughly every 60 seconds on trading days, and daily ECB/FRED reference rates for the remaining pairs. Full history goes back to 1999 across all 465 supported pairs.
Every plan, including free, gets the same data freshness. Paid tiers add throughput and commercial-use licensing: Basic is $10/mo for 100,000 calls/month, Pro is $30/mo for up to 1,000,000 calls/month. It also includes an MCP server and llms.txt for AI-agent integration, a batch /convert endpoint, and a /range endpoint for historical queries.
Every response is source-labeled, so you always know whether a given rate is live or daily-reference.
