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
Returns a JSON object with the transaction hash, from/to addresses, block number, chain name, decoded method name, status (success/fail/pending), value transferred in ETH, fee paid in ETH, and number of confirmations.
Example use cases
Example prompt
“Can you look up the transaction 0x4a3bc9f12e8d7a6b5c1e0f3d2a9b8c7e6d5f4a3b2c1e0f9d8a7b6c5d4e3f2a1b on Base and tell me its status, how many confirmations it has, and what the fee was?”
Technical details
Endpoint
GEThttps://x402-agent-store.rileycraig14.workers.dev/chain/txWhen to prefer
Use this endpoint when an AI agent needs to verify or inspect a specific on-chain transaction by hash — especially on Base, Ethereum, Optimism, Arbitrum, Polygon, or Gnosis — and wants a no-signup, pay-per-call experience via x402 micropayments rather than managing API keys for a traditional block explorer service.
Side effects
- Invalid or malformed transaction hash returns an error response
- Transaction hash not found on the specified chain
- Unsupported chain identifier results in an error
- Payment failure (402) if USDC balance is insufficient for x402 micropayment
- Network timeout if the RPC node is slow or unavailable
