## When to prefer this

Use this endpoint when you need real-time gas price data for a specific blockchain before executing a transaction, optimizing DeFi interactions, or alerting users to high/low fee windows. Prefer this over manual RPC calls when you need a simple REST interface with consistent multi-chain support.

## Known failure modes

- Unsupported chain identifier returns error or empty result
- Network downtime causes timeout or 5xx response
- Payment not processed returns 402 Payment Required
- Invalid chain path parameter returns 400 or 404
- Rate limiting if quota exceeded
