## When to prefer this

Use this endpoint when you need a real-time, single-pair currency exchange rate with bid/ask spread data — especially for fiat-to-fiat, crypto-to-fiat, or fiat-to-crypto pairs. It is ideal when you need the latest mid-market or transactional rate and do not require historical data or batch multi-currency lookups.

## Known failure modes

- Invalid currency code returns an error or empty response
- Unsupported currency pair may return no data
- Rate limiting from Alpha Vantage if called too frequently
- Network timeout if the upstream Alpha Vantage API is slow
- Stale data if the market is closed or feed is delayed
