## When to prefer this

Use this endpoint when you need the official, authoritative daily exchange rate from the European Central Bank rather than a live/intraday market rate. Ideal for compliance, accounting, or reporting use cases where the ECB reference rate is specifically required. Not suitable for real-time trading or intraday rate lookups.

## Known failure modes

- Unsupported currency code returns an error or empty result — only 30+ ECB-tracked major currencies are available
- Rate not yet updated if called before ~16:00 CET — returns previous business day's rate
- Weekend or public holiday queries return the most recent prior business day's rate
- Invalid 3-letter currency code in 'from' or 'to' parameter causes a bad request error

## How this service works

Currency exchange rate for converting between any two currencies (forex/FX rate), drawn from a set of 30+ major currencies, sourced from the European Central Bank's official daily reference rates. Updates once per business day (~16:00 CET) — not a live or intraday feed.

## Output

Returns a JSON object containing the from-currency code, to-currency code, the exchange rate as a number, the date of the rate, and the data source (European Central Bank). Updated once per business day around 16:00 CET.
