Lookproof

Run the mail configuration check (MX, SPF, DMARC) on up to 20 domains in one request. Results keep the input order, and items that fail for a technical reason come with a token for a free retry. Use when an agent must audit many domains at once, for example a customer list or a portfolio of brands.

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.lookproof.dev/v1/mail/check/bulk", { method: "POST" });
console.log(await res.json());
