## When to prefer this

Choose this endpoint when you need official, authoritative currency conversion using European Central Bank reference rates — ideal for financial reporting, compliance, invoicing, or any scenario requiring a neutral, non-commercial exchange rate. Prefer this over market-rate APIs when ECB rates are contractually or legally required, or when you need a specific historical date's rate.

## Known failure modes

- Unsupported currency code returns an error (ECB only publishes rates for ~30 major currencies)
- Future date or weekend/holiday date may return no data since ECB does not publish rates on non-business days
- Invalid date format (not YYYY-MM-DD) causes a validation error
- Amount of zero or negative value may return an error or zero result
- Very old historical dates may not be available in the ECB dataset

## How this service works

Convert an amount between two currencies at the European Central Bank reference rate, latest or on a past date.

## Output

Returns the converted monetary amount in the target currency, the exchange rate applied, the currency pair, and the date of the ECB reference rate used for the conversion.
