Blackwood State Email Batch

Use when you need bulk email validation, email list verification or to verify email lists before a send or import. Do not use for one address (email-check is cheaper), proving a mailbox exists (no SMTP probe) or sending email. Returns JSON checking up to 20 email addresses in one call: syntax, MX records, disposable, free and role flags, SPF, DMARC and a verdict each, plus counts by verdict for 0.

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://x402-gateway.blackwoodstate8.workers.dev/v1/email-batch", { method: "POST" });
console.log(await res.json());
