Technical details
Endpoint
POSThttps://coinrailz.com/x402/service/gas-price-oracleWhen to prefer
Use this endpoint when an agent needs real-time, multi-chain gas price data with USD cost estimates in a single call — particularly useful for DeFi automation, cross-chain routing decisions, or cost-optimization workflows where knowing the cheapest network to transact on is critical.
Side effects
- Unsupported chain identifier returns error or is omitted from results
- Network congestion may cause stale or unavailable gas data for specific chains
- Payment failure (insufficient USDC balance) results in 402 error before data is returned
- Empty chains array may return all supported chains or an error depending on implementation
