Currency Exchange Rate API
ECB FX rates with batch convert, timeseries & cache headers
Most currency APIs give you one rate, one request at a time — and never tell you if the data is fresh or cached. Currency Exchange Rate API is built differently. Convert multiple amounts in a single batch request to save quota. Pull historical rates over a date range for charts, accounting, and BI pipelines. Every response includes source, stale, X-Cache, and X-Last-Updated so you always know exactly what you're getting — no surprises in production.
I built this after integrating several currency APIs and constantly running into the same problems: no batch endpoint (so 50 invoices = 50 requests), no timeseries (so building charts meant stitching together daily calls), and zero visibility into whether the rate I got was fresh or cached.
This API solves all three. Batch convert, timeseries, and full cache transparency via response headers and fields. Sourced from ECB, cross-rate math for any base currency, no database needed.
Happy to answer any questions — and if you've had the same frustrations with other FX APIs, would love to hear what else is missing.
