Agent Paywire

Check whether a public URL exposes L402, x402, or MPP discovery. Send url as a query parameter. POST JSON {"url":"https://..."} is the same check. Two free reports per client per 24 hours, then 0.05 USDC. A request without url is the payment challenge and does not use a free report.

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://api.agentpaywire.com/v1/check", { method: "GET" });
console.log(await res.json());
