Technical details
Endpoint
POSThttps://coinrailz.com/x402/gas-price-oracleWhen to prefer
Use this endpoint when an AI agent needs up-to-date gas fee data across multiple chains simultaneously with USD cost conversion already included, especially when building DeFi trading flows, transaction cost estimators, or cross-chain routing logic where knowing the cheapest chain to transact on matters.
Side effects
- Unsupported chain identifier returns an error or empty result
- Payment of 0.1 USDC not received — 402 payment required response
- Upstream node provider unavailable causing stale or missing gas data
- Invalid request body format returns a parsing error
- Network congestion causing delayed response
