x402
Industrial Platform Web Tools – Gas Price Lookup is a paid API for AI agents from x402-gateway-production-1f21.up.railway.app, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-11).
Returns current gas price data for a specified EVM-compatible blockchain network (Base or Ethereum mainnet)
Price / call$0.001

How this service works
Gas price in the Roundhouse canonical contract: CAIP-2 chain to current base_fee_gwei and as_of. Recurring fee-state primitive for transaction timing and autonomous execution.
Output
A JSON object containing the current gas price status and fee data for the requested EVM chain, indicating network readiness and current pricing in wei or gwei.
Example use cases
Pre-transaction fee check
“Before I submit this on-chain transaction, can you check what the current gas price is on Base so I know how much it'll cost me?”
Ethereum mainnet gas monitoring
“What's the gas price on Ethereum mainnet right now? I want to know if it's a good time to send a transfer.”
Automated DeFi cost gating
“Check the current gas price on eip155:8453 — I only want to proceed with the swap if fees are below a certain threshold.”
Technical details
Endpoint
GEThttps://x402-gateway-production-1f21.up.railway.app/gas-price?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real-time gas price data for Base (eip155:8453) or Ethereum mainnet (eip155:1) via a machine-payable micropayment API. Prefer it for automated agent workflows that need fee estimates before submitting transactions, or for monitoring gas price trends without setting up direct RPC connections. It is particularly suited for AI agents operating on the x402 payment protocol that need a simple, pay-per-call gas oracle without managing API keys.
Side effects
- Unsupported chain ID returns validation error — only eip155:8453 (Base) and eip155:1 (Ethereum mainnet) are accepted
- Missing required 'chain' query parameter returns 400 bad request
- Network connectivity issues to the RPC provider may return stale or error responses
- Payment failure (x402 protocol) prevents the response from being returned
