Transaction receipt (decoded transfers)

Full receipt for a transaction hash in one call: status, block, from/to, value, gas used vs limit, effective gas price, total fee, tx type, calldata selector, contract created, plus every ERC-20 / ERC-721 / ERC-1155 Transfer event decoded locally from the logs (token, from, to, amount, tokenId) and the list of contracts that emitted logs. Send POST /api/tx-receipt with the required field hash and pay $0.003 per call over x402 or MPP (there is no free tier). It returns a JSON object with network, chainId, hash, status, blockNumber and 22 more.

Receipt and transaction are fetched in a single batched request. 404 (not charged) when the hash is unknown on that chain; a seen-but-unmined tx answers with status pending.

Parameters

Example request

curl -i -X POST https://agent402.tools/api/tx-receipt \
  -H "Content-Type: application/json" \
  -d '{"hash":"0x214b3526ee64f7eabfc94ea536b8680bd95a2da634ebf5149aea189d311be56b","network":"ethereum"}'

Without payment this returns HTTP 402 Payment Required with the exact price for tx-receipt; any x402 v2 or MPP client pays it and retries.

From an MCP client

catalog.call {
  "slug": "tx-receipt",
  "params": {
    "hash": "0x214b3526ee64f7eabfc94ea536b8680bd95a2da634ebf5149aea189d311be56b",

}

The hosted connector at https://agent402.tools/mcp needs a payment for tx-receipt; the stdio package pays it from a wallet or from AGENT402_CREDITS_KEY. Local install: npx -y agent402-mcp.

Errors and behavior

• hash is required. An input the tool rejects returns an HTTP 4xx whose body carries error, tool, expected, required and example, so the caller can correct it.
• A paid call that ends in any status of 400 or above is not charged over x402, MPP or a prepaid credits key: settlement is cancelled when the tool fails. The exception is a Tempo push credential, a transfer the buyer sent before the call: it settles before the tool runs, so if the tool then fails the payment is recorded as a refund owed to the paying wallet.
• Wallet-only: this tool reaches the network or stored state, so it has no proof-of-work tier. A prepaid card-credits key issued earlier (Authorization: Bearer a402_...) also pays it.
• A GET or HEAD to /api/tx-receipt returns the same 402 quote, so the price can be read without a body.
• An Idempotency-Key header makes a retried paid call replay the first 200 instead of charging again (an answer larger than 1 MB is not replayed).

Paid call (JavaScript agent)

import { wrapFetchWithPayment } from "@x402/fetch";
import { x402Client } from "@x402/core/client";
import { registerExactEvmScheme } from "@x402/evm/exact/client";
import { privateKeyToAccount } from "viem/accounts";

const client = new x402Client();
client.setSpendControls?.(false); // keep your own spending ceiling in code
registerExactEvmScheme(client, { signer: privateKeyToAccount(KEY) });
const payFetch = wrapFetchWithPayment(fetch, client);

const res = await payFetch("https://agent402.tools/api/tx-receipt", {
  method: "POST",
  headers: { "Content-Type": "application/json" },
  body: JSON.stringify({
    "hash": "0x214b3526ee64f7eabfc94ea536b8680bd95a2da634ebf5149aea189d311be56b",
    "network": "ethereum"
  }),
