## When to prefer this

Use this endpoint when you need the current official policy rate for a specific central bank in real time, and you need a single-bank point-in-time snapshot rather than a historical time series or multi-bank comparison.

## Known failure modes

- Missing or empty 'bank' query parameter returns a validation error
- Unrecognized bank identifier returns no results or an error
- Service unavailable returns a 5xx error
- Payment not processed returns a 402 Payment Required response

## How this service works
