How this service works
Pay-per-call on-chain API for AI agents and developers: wallet audits, token safety audits (honeypot detection), live gas prices, token prices, transaction receipts, balances, ENS resolution, block data, ERC-20 allowances, transaction simulation, swap quotes and multicall batches — all computed on-chain via public RPCs (no external market API). Pay per request in USDC on Base via the x402 exact scheme (EIP-3009 transferWithAuthorization). No API key, no signup, no subscription.
Output
Returns a structured on-chain receipt object containing: transaction status (success or reverted), block number, gas used, from address, to address, ETH value transferred, and the count of event logs emitted by the transaction.
Example use cases
Confirm payment landed on-chain
“I just sent a USDC payment on Base with tx hash 0x4f3a...91b2 — can you confirm it went through, what block it landed in, and how much gas was used?”
Diagnose a reverted smart contract call
“My contract interaction on Base with hash 0x7c2d...88fa seems to have failed — can you pull the receipt and tell me if it reverted, which block it's in, and the from/to addresses?”
Audit a wallet transaction for records
“I need the full on-chain receipt for Base tx 0x1e9b...3c44 — status, block number, gas consumed, sender and recipient addresses, value transferred, and number of logs emitted.”

Endpoint
GEThttps://x402-audit.tatschluizguilherme.workers.dev/txWhen to prefer
Choose this endpoint when you need a quick, cheap on-chain receipt lookup for a specific transaction hash on Base without relying on a block explorer API key (Etherscan, Basescan, etc.). Ideal for agents verifying payment confirmations, diagnosing reverts, or auditing specific transactions programmatically at $0.10 per call.
Side effects
- Transaction hash not found or not yet indexed — returns not-found or null receipt
- Invalid or malformed tx hash format — returns validation error
- Transaction still pending (not yet mined) — receipt unavailable
- Network/RPC error on Base — returns upstream error
- Incorrect network (tx exists on a different chain) — returns null receipt
