How this service works
Look up any transaction by hash: confirmation status (success/failed/pending), block number, confirmations, value, from/to, fee paid, gas used, and the decoded method. The read every settlement, trading, and payment agent polls after sending a tx to confirm it landed. Across Base, Ethereum, Optimism, Arbitrum, Polygon, Gnosis. Free upstream (Blockscout); one paid call instead of running your own RPC.
Output
A JSON object containing the transaction hash, from/to addresses, the chain it occurred on, the decoded method name (e.g. 'transfer'), status ('success' or 'failed'), the block number, number of confirmations, ETH value transferred, and ETH fee paid.
Example use cases
Example prompt
“Can you look up the transaction 0x4a2f8c1e9b7d3f05c6a8e2d1b4f7a9c3e5d2f1b0a8c4e6d9f2a5b8c1d4e7f0a3 on Base and tell me whether it succeeded, how many confirmations it has, and what value was transferred?”
Technical details
Endpoint
GEThttps://store.agentexchange.work/chain/txWhen to prefer
Use this endpoint when an AI agent needs to verify, decode, or retrieve details of a specific on-chain transaction across EVM-compatible chains (Base, Ethereum, Optimism, Arbitrum, Polygon, Gnosis) without needing an API key — pay-per-call via x402 USDC micropayment makes it ideal for lightweight, on-demand transaction lookups in autonomous agent workflows.
Side effects
- Invalid or malformed transaction hash returns an error
- Transaction hash not found on the specified chain
- Unsupported chain identifier causes a 400 error
- Transaction still pending with zero confirmations
- Network or RPC node timeout causing delayed response
