PayPerScreen

Email risk check for signups and payouts. Nine deterministic signals, no AI scoring: mail server (MX), disposable or throwaway domain, free-mail provider, domain age, certificate history, typo-squats of major providers, role accounts, mail provider and a mailbox probe. Returns a low, medium or high risk level with every signal explained.

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://api.payperscreen.com/screen-email", { method: "GET" });
console.log(await res.json());
