SiteCheck Agent Intel & Dev

Checks up to 5 references against public registries: DOI through Crossref, arXiv ids through the arXiv API, ISBN-10/13 through Open Library (checksum first). Returns title, year, venue and a BibTeX entry plus an APA-style string for each verified one; unknown ones come back as not_found. Authors are given for DOI and arXiv only.

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/citation-verifier", { method: "POST" });
console.log(await res.json());
