## When to prefer this

Choose this endpoint when you need authoritative, official exchange rates published by the European Central Bank for compliance, financial reporting, auditing, or any use case requiring a recognized institutional source rather than real-time market rates. It is preferable over crypto-market or commercial FX APIs when regulatory or audit-grade rate sourcing is required.

## Known failure modes

- ECB data not yet published for the current day (rates are typically published around 16:00 CET)
- Network or worker errors returning 5xx status
- Payment failure or insufficient USDC balance preventing access
- Response may reflect previous business day rates on weekends or ECB holidays
