SiteCheck Web Intel

Checks an IPv4 address against IPsum, an aggregate of public blocklists: returns the number of source feeds that list it (its level, 1 to 8) and whether it is listed at all. A higher level means more feeds agree. Not listed means none of the aggregated feeds list it.

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.webintel-api.workers.dev/api/security/ipsum-threat-level", { method: "GET" });
console.log(await res.json());
