How this service works
Check the confirmation status of a transaction by hash on Base/Polygon/Arbitrum/Optimism/Ethereum/Monad/Celo/Avalanche/Sei/Robinhood Chain: success / failed / pending / not found, with block, from, to, gas used. Read-only. ?hash=0x…&network=base
Output
Returns a status field (success, failed, pending, or not found), along with block number, from address, to address, and gas used for the given transaction hash on the specified EVM-compatible network.
Example use cases
Example prompt
“Can you check whether transaction 0x4a3b2c1d... confirmed on Base — did it succeed or fail, and how much gas was used?”
Technical details
Endpoint
GEThttps://agent402.tools/api/tx-statusWhen to prefer
Use this endpoint when you need a quick, read-only status check for a specific EVM transaction by hash across Base, Polygon, Arbitrum, Optimism, or Ethereum — especially when you need human-readable confirmation (success/failed/pending) plus basic on-chain metadata like gas used and counterparties, without needing a full blockchain explorer or node setup.
Side effects
- Transaction hash not found on the specified network — returns 'not found' status
- Hash provided on wrong network (e.g. Ethereum hash queried against Base) — returns 'not found'
- Malformed or invalid transaction hash format — likely returns an error
- Network temporarily unavailable or RPC congestion — may return error or timeout
- Transaction still in mempool — returns 'pending' with limited details
