Use this endpoint when you need a real-time or near-real-time spot forex exchange rate for a specific currency pair and are comfortable paying $0.05 USDC per call via x402. Prefer this over free/public APIs when reliability and Twelve Data's coverage are required, especially for less common currency pairs.

## Known failure modes
