EVM Transaction Receipt Lookup
x402
EVM Transaction Receipt Lookup is a paid API for AI agents from flat-rate-llm.kikoribera03.workers.dev, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-14).
Returns the receipt of an on-chain transaction: success/revert status, gas used, fee paid in Ether, and number of logs emitted, via eth_getTransactionReceipt.

How this service works
60 paid endpoints with no metering, no API key and no account. Each endpoint has one flat price per call, whatever the size of the request: LLM completions with automatic failover across several large models, read-only EVM tooling over Base, Ethereum, Polygon, Arbitrum and Optimism, and pure crypto utilities that touch no network.
Output
A JSON object indicating whether the transaction was found on-chain (found: true/false), its outcome (status: 'success' or 'reverted'), the amount of gas consumed (gasUsed), the actual fee paid denominated in Ether (feePaidEther), and the number of logs/events emitted (logs).
Example use cases
Confirm token transfer landed
“I just sent some USDC on Ethereum — the tx hash is 0xabc123def456... — can you check if the transfer succeeded and tell me the gas fee I actually paid?”
Debug a failed smart contract call
“My transaction 0x9f3e7a2b1c4d5e6f... on Ethereum seems to have failed — can you pull the receipt and tell me if it reverted and how many logs it emitted?”
Audit gas spend for a batch of transactions
“Check the receipt for tx 0x1a2b3c4d5e6f7a8b... on Polygon — I need the exact gas used and the fee paid in Ether so I can log it for accounting.”

Endpoint

Use this endpoint when you need a fast, pay-per-call lookup of a single transaction's on-chain outcome without managing your own RPC infrastructure. Ideal for agents that need to confirm whether a transaction succeeded, how much gas it consumed, or how many events it triggered, especially in automated workflows where you submit a tx and then need to poll for its receipt. Prefer this over general-purpose Ethereum RPC libraries when you want a clean JSON response with pre-computed feePaidEther without doing the arithmetic yourself.
Side effects
- Transaction hash not yet mined — returns found: false if the tx is still pending or doesn't exist
- Invalid or malformed transaction hash — returns an error or found: false
- Unsupported chain ID — endpoint may return an error if the requested chain is not supported
- Network timeout or RPC node unavailability — may return a service error
- Querying a very old transaction on a pruned node — may not be found
