x402 Web Tools

Check a web page for changes: each call compares the page's readable text with your previous check of the same URL (kept per paying wallet for 90 days) and returns whether it changed, when you last checked, and the added and removed lines. The first call records the page. Use name to keep several watches of one URL apart.

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://web.kagurazaka.dev/v1/watch", { method: "GET" });
console.log(await res.json());
