Transaction Status
x402
Transaction Status is a paid API for AI agents from www.x402financialdata.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-13).
Returns the success/failure status and contract execution error detail for an Ethereum transaction hash, catching reverted contract calls that bare confirmation checks miss.

How this service works
Success/failure status for an Ethereum transaction hash in one call: post-Byzantium receipt status plus contract execution error detail, from Etherscan's V2 API -- catches the 'transaction confirmed but the contract call actually reverted' case a bare confirmation check misses. $0.01/call.
Output
Returns the post-Byzantium receipt status (success or failure) for the transaction plus contract-level execution error detail — specifically surfacing cases where the transaction was confirmed on-chain but the underlying smart contract call reverted, along with the revert reason if available.
Example use cases
DeFi swap confirmation check
“I just submitted a Uniswap swap and got a confirmation, but I'm not sure the trade actually went through — can you check tx hash 0x4dfa7b1be6578326be24ad2d330e7baf23230e18c2d2c67d8f41798e0e764b0b and tell me if the contract call succeeded or reverted?”
NFT mint failure diagnosis
“My NFT mint transaction shows as confirmed on Etherscan but I didn't receive the token — please check 0x7a9d8b2c3f1e4567890abcdef1234567890abcde and tell me if the contract execution actually succeeded or if it reverted.”
Automated payment pipeline validation
“Before I mark this payment as complete in our system, verify that Ethereum transaction 0xabc123def456789012345678901234567890abcdef succeeded at the contract level, not just that it was mined.”
Technical details
Endpoint
GEThttps://www.x402financialdata.com/transaction-status/:tx_hashWhen to prefer
Use this endpoint when you need to distinguish between a transaction being mined and a contract call actually succeeding — critical for DeFi interactions, NFT mints, and any smart contract invocation where a revert would leave the transaction confirmed but the intended action unfulfilled. Prefer this over a bare block confirmation check whenever contract execution correctness matters.
Side effects
- Invalid or malformed transaction hash returns an error
- Transaction hash not found on Ethereum mainnet
- Only 'eth' chain is supported; other chains return unsupported chain error
- Network or Etherscan API downtime may cause lookup failures
- Very recent transactions not yet indexed may return not-found
