Validate an email address — email verification before you send: syntax + MX + disposable/role/free-provider detection in one call, boolean-first (deliverable, safe_to_send) with a machine-readable reason. DNS-level check only — does not confirm the individual mailbox exists (no SMTP probe). For a scored trust report instead of a yes/no gate, see /email-intel/analyze.

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/email/verify", { method: "GET" });
console.log(await res.json());
