Forest Web

Verify email syntax and public DNS readiness with a bounded deterministic preflight. Forest checks normalized syntax, MX/address records including explicit null MX, and curated role/free/disposable-domain signals, then returns a conservative safe-to-attempt decision. It never connects to SMTP, sends mail, authenticates, stores customer mailboxes or claims that a mailbox exists. Base mainnet USDC

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://http--forest-gas-station-mainnet--lcjl27p8lmjs.code.run/email/verify", { method: "POST" });
console.log(await res.json());
