Indicative rates over a clean REST API, live every day including weekends. Each response carries its source, market_session, and a timestamp, so you always know how fresh a rate is.
Many FX APIs freeze at Friday's fix. exchangerate.dev keeps updating through the weekend, about every 60 seconds.
Each request is processed in roughly 20ms server-side. Frankfurter-compatible params let you swap in without rewriting your client.
Every rate ships with its source, market_session, and timestamp, so you know if it's a live quote or a daily fix.
Indicative rates only, not for settlement. Aggregated market data + public reference rates; ±5–15 bps.
