SiteCheck Agent Intel & Dev

Checks the named entities in an AI answer (up to 5 capitalised names) against Wikidata: each name is marked found or not found, with its Wikidata ID and description, and sentences containing a year are listed for review. It checks that entities exist, not that claims about them are true, so a found entity can still have a wrong fact.

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.fadeandco.workers.dev/api/agent-intel/hallucination-claim-checker", { method: "POST" });
console.log(await res.json());
