Factline

Use when you need to judge whether a website or email domain is trustworthy: registration date and domain age (RDAP), expiry, registrar, nameservers, email setup (MX, SPF, DMARC), disposable-email domains, and a low/medium/high risk with flags such as 'registered 4 days ago', a common sign of scam shops. Accepts a domain, URL or email.

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://factline.dev/v1/domain/check", { method: "GET" });
console.log(await res.json());
