EVM Transaction Lookup by Hash
x402
EVM Transaction Lookup by Hash is a paid API for AI agents from dt0ur.online, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-01).
Fetches full transaction details by hash on major EVM chains, including status, block info, gas, fees in USD, method selector, and decoded ERC-20 transfers.

How this service works
Look up a transaction by hash on base, ethereum, arbitrum, optimism, polygon, bsc: status (success/reverted/pending), block and timestamp, from/to, value, gas used, fee in native coin and USD, method selector, created contract, and decoded ERC-20 transfers with token symbols and amounts. Transaction and receipt in one call.
Output
Returns transaction status (success/reverted/pending), block number, timestamp, from and to addresses, ETH/native value, gas used, fee in native coin and USD, method selector, any created contract address, and a list of decoded ERC-20 transfers including token symbols and amounts — all from a single call combining the transaction and its receipt.
Example use cases
Verify DeFi swap outcome
“I just submitted a swap on Uniswap on Ethereum — the tx hash is 0xabc123...def456. Did it succeed, and what tokens were transferred and in what amounts?”
Audit gas cost on Polygon
“Can you check transaction 0x7f8e9d...c0b1a2 on Polygon and tell me the exact gas fee it cost in MATIC and in USD?”
Debug reverted transaction on Base
“My transaction 0x1d2e3f...a4b5c6 on Base seems to have failed — can you confirm whether it reverted and tell me what method it was trying to call?”
Technical details
Endpoint
POSThttps://dt0ur.online/api/onchain/tx?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a single call that combines both the raw transaction and its receipt data across multiple EVM chains, including decoded ERC-20 transfer events and USD-denominated fee estimates. It is ideal for agents that need to verify transaction outcomes, audit gas costs, or trace token flows without having to hit multiple RPC endpoints or decode logs manually.
Side effects
- Transaction hash not found on the specified chain — returns error indicating hash is unknown
- Invalid hash format — returns validation error if hash is not 0x + 64 hex chars
- Chain not supported — returns error if chain value is outside the allowed enum
- Transaction still pending — status returned as pending with no receipt data yet
- RPC timeout or node unavailability — upstream chain node may be temporarily unreachable
