How this service works
Deterministic compliance verification (IBAN, sanctions, onchain address) with XDR-1 signed receipts, plus Ethereum chain-data endpoints. Paid per call via x402 on Base (USDC).
Output
Returns a JSON object containing the current Ethereum mainnet gas price as a string result and a network identifier (e.g. 'ethereum-mainnet'). The response is chain data fetched live from the Ethereum network at call time.
Example use cases
Pre-transaction gas fee check
“Before I send this ETH transfer, can you pull the current Ethereum mainnet gas price so I know if fees are reasonable right now?”
DeFi bot cost estimation
“I'm running an arbitrage script and need the live Ethereum gas price to calculate whether the trade is still profitable — can you fetch it?”
Gas fee monitoring alert
“Check the current Ethereum mainnet gas price for me and let me know if it's below 20 gwei so I can time my contract deployment.”
Technical details
Endpoint
GEThttps://verify.code402.dev/v1/chain/gas-price?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, pay-per-call lookup of Ethereum gas price without maintaining a dedicated RPC connection or subscription. It's ideal for agents that need occasional gas price checks with verifiable receipts (XDR-1 signed) and micropayment billing via USDC on Base rather than a monthly API plan.
Side effects
- Ethereum node unavailable or rate-limited — may return 5xx error
- Payment not processed via x402 — returns 402 Payment Required before delivering data
- Stale or delayed data if underlying RPC node is behind the chain tip
- Invalid or missing x402 payment header — request rejected before execution
