Mail Security Tools

Get the exact SPF, DKIM and DMARC records to publish, with steps for your DNS host. $1 USDC on Base per call. Reads live MX, NS, SPF, DKIM and DMARC, detects the mail provider and DNS host, and returns records in order with a staged DMARC rollout. Non-sending domains get a lock-down set. Bad input 400, unknown domain 404, not charged. Don't use this for a quick grade; use /v1/score.

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.mailsecuritytools.com/v1/fix-plan", { method: "GET" });
console.log(await res.json());
