Check a sales lead before outreach — one call verifies the email address (syntax, MX, disposable/role/free-provider), the company's email setup (SPF/DKIM/DMARC) and its domain age, and returns a verdict: yes, risky or no, with machine-readable reasons. Free personal mailboxes skip the company checks. DNS-level only — no SMTP mailbox probe.

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://netintel.dev/lead/check", { method: "POST" });
console.log(await res.json());
