Lint any x402 endpoint before you pay it: fetches the unpaid 402 challenge (v1 body or v2 PAYMENT-REQUIRED header), decodes price/network/asset/payTo, flags non-USDC assets, testnets, missing bazaar metadata and malformed fields.

Call it from code

This API is run by its own provider and paid directly through x402. We list it so you can find it; we don't route or hold the payment.

import { x402Client, wrapFetchWithPayment } from "@x402/fetch";
import { registerExactEvmScheme } from "@x402/evm/exact/client";

const client = new x402Client();
registerExactEvmScheme(client, { signer: agentAccount });

const pay = wrapFetchWithPayment(fetch, client);
const res = await pay("https://mm-agent-utils.gferrigno.deno.net/v1/x402-check", { method: "GET" });
console.log(await res.json());
