Mail Security Tools

Score email security (SPF, DMARC, DKIM, MX) for up to 100 domains in one call. $0.5 USDC on Base per call. Returns per-domain score, grade and issues plus a summary: grade counts, missing DMARC/SPF and worst 10. Bad input 400 and widespread DNS failure 502, not charged. Don't use this for one domain; /v1/score costs less.

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/bulk-score", { method: "GET" });
console.log(await res.json());
