About

AllRatesToday serves real-time mid-market FX rates for 160+ currencies, refreshed every minute, with official SDKs for JS, Python, PHP, Go, and Rust. The free tier needs only a key from registration: 300 requests, 10 per minute, no credit card. Unusually for a finance API, it also ships a live MCP server purpose-built for AI agents, so your agent can pull exchange rates as a native tool call.
