Payment receipt for an x402 or USDC payment from its transaction hash

$0.01 per call · failed calls are never charged · no account or subscription: pay per call with a card key or USDC

Turn a settled x402 or USDC payment into a receipt to file: from the transaction hash, the payer, payee, amount, time, block, status and whether it was an EIP-3009 authorization (the x402 exact scheme), on Base, Ethereum, Arbitrum, Optimism or Polygon, with a stable receipt id and a SHA-256 of a canonical text for bookkeeping. Optionally name what was bought. Never signs. Use to keep proof of a purchase after an agent pays.

Inputs

Request

Over HTTP, with a card key from /credits:

curl -H "Authorization: Bearer adt_…" "https://agent-data-tools.revmesh2074.workers.dev/x402/receipt?hash=0x778c8c1b1fd1b320bf045eae0af7274e74a9e2e1f83c34ec96d9f825aea3b933"

Or one of your 3 free calls, no key:

curl "https://agent-data-tools.revmesh2074.workers.dev/x402/receipt?hash=0x778c8c1b1fd1b320bf045eae0af7274e74a9e2e1f83c34ec96d9f825aea3b933&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 or Solana over x402; Base or Tempo over MPP) and retries.
