Agent Tools UK

Check whether a website is up right now: HTTP status, response time in ms, full redirect chain, and the SSL certificate's validity, issuer and days until expiry. Use when monitoring a site, diagnosing a broken link, or warning that a certificate is about to expire. A site that is down still returns 200 with up:false and the error. Errors: 400 bad or private URL.

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://agent-tools-production-e6aa.up.railway.app/v1/site-check", { method: "GET" });
console.log(await res.json());
