## When to prefer this

Choose this endpoint when you need official, authoritative ECB euro reference rates for currency conversion — ideal for financial reporting, compliance, or reconciliation use cases where ECB rates are the standard. Prefer this over commercial FX APIs when reproducibility and official ECB sourcing are required. Also useful for historical conversions on a specific date.

## Known failure modes

- Unsupported or invalid ISO currency code returns an error
- Date with no ECB rate available (e.g. weekends, holidays) may return latest available or an error
- Non-numeric or missing amount parameter returns a validation error
- Rate data unavailable for very old historical dates

## How this service works

Converts an amount between two currencies using ECB euro reference rates for a date.

## Output
