Example prompt: What's the current ECB official exchange rate for euros against the US dollar, and while you're at it, what is the ECB's current key interest rate?

## When to prefer this

Use this endpoint when you need official ECB-published EUR exchange rates or ECB key interest rates, especially for financial applications, economic analysis, or regulatory compliance that requires authoritative central bank data rather than commercial FX feeds.

## Known failure modes

- Unsupported currency pair returns an error or empty result
- ECB data temporarily unavailable due to publication schedule
- Rate type parameter not recognized
- Network timeout or payment failure (x402 micropayment)
