Onchain transaction verification: POST a Base tx hash, returns whether it confirmed or reverted, confirmation count, the actual ERC20 token transfers that occurred (with token labels), ETH value moved, gas used and gas cost. For AI agents to verify an action truly executed before proceeding (did the payment land, did the swap go through, did it revert). Machine-readable execution receipt from onchain truth.
Start with a quote-only recipe. Payment signing stays in your project.
const response = await fetch("https://api.x402node.dev/wallet/tx-verify", {
method: "GET",
});
console.log(response.status);
console.log(Object.fromEntries(response.headers));
console.log((await response.text()).slice(0, 1000));
// A valid 402 is a quote, not a completed paid call.This sends no payment. Inspect the 402 response before adding a wallet-enabled client.

EVIDENCE
Each record has an exact-route quote outcome. Unresolved templates and potentially mutating methods are labeled instead of being invoked without provider-specific test input. A quote is still separate from a settled paid call.
