## When to prefer this

Choose this endpoint when you need official, authoritative ECB foreign exchange rates — particularly for EUR-based or European finance contexts, compliance use cases, or when institutional accuracy matters over real-time market tick data. It is ideal for invoicing, financial reporting, and travel budget estimation where official reference rates are preferred over live interbank spreads.

## Known failure modes

- Invalid ISO 4217 currency code returns an error or empty result
- ECB data unavailable or stale during weekends/holidays may return last published rate
- Omitting base currency may default to EUR or return a validation error
- Target currency not covered by ECB may return a missing or null rate

## How this service works

## Output
