Currency Exchange — entry 013 of 18
Exchangerate.dev
Exchangerate.dev is a lean, Frankfurter-compatible FX endpoint aimed at fintech apps, trading tools, and AI agents that want genuinely intraday pricing rather than a once-daily fix: its supported currencies refresh roughly every 60 seconds through the trading week, and every quote is tagged with its source and timestamp so callers can tell a live tick from a stale daily rate. It requires no API key or card to start, positioning itself as a near drop-in replacement for Frankfurter's response shape for teams that need faster-moving data.
