Monitor a web page for changes — fetch a URL, compare it with your previous check and return changed true/false, the added and removed lines, the percent changed and the new content only when it changed. First call stores the baseline; repeat with the same watch_id from your cron. Works on HTML (readable text), JSON (canonical keys) and plain text; conditional GET; no API key.

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://netintel.dev/web/monitor", { method: "GET" });
console.log(await res.json());
