Returns JSON: httpStatus, isX402, x402Version, decoded accepts (network, asset, USD amount, payTo, EOA or contract), discovery metadata presence, and pass/warn/fail checks. Any HTTP answer from the target, even 4x

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://horizonpulse.dev/api/x402-check", { method: "GET" });
console.log(await res.json());
