Optimism transaction

$0.003 per call · failed calls are never charged · no account or API key needed

Look up a Optimism transaction by hash: sender, recipient, value in ETH, nonce, gas limit, the 4-byte function selector and its block. Use to see what was sent or whether it exists; for success or failure and fees paid use op_receipt, for emitted events op_logs. Input is a 0x-prefixed 64-hex hash; an unknown hash returns 404, uncharged.

Request

Over HTTP, with a card key from /credits:

curl -H "Authorization: Bearer adt_…" "https://agent-data-tools.revmesh2074.workers.dev/op/tx?hash=0x721f3e9a996da49e2a8929bd2dd42e0f51344c11d7ca7bc3328fda349cdfae89"

Or one of your 25 free calls, no key:

curl "https://agent-data-tools.revmesh2074.workers.dev/op/tx?hash=0x721f3e9a996da49e2a8929bd2dd42e0f51344c11d7ca7bc3328fda349cdfae89&trial=1"

Without a key, the same URL answers 402 Payment Required with x402 and MPP terms, so an agent with a wallet pays per call in USDC (Base, Polygon, Arbitrum, Monad, World Chain or Tempo) and retries.
