DNS TXT record lookup — a domain's TXT records as a clean JSON list: SPF, DKIM and DMARC policy strings plus site-verification and domain-ownership tokens, for email-authentication and domain-verification checks.
GET https://dns.use.x402atlas.com/txtListed in 3 directories: bazaar, x402-list, x402-new. First seen 5 Sept 2026.
The endpoint answers an unpaid request with an HTTP 402 and a payment challenge. @x402/fetch signs it, pays in USDC, and retries — you get the result back in one call.
import { wrapFetchWithPayment } from "@x402/fetch";
import { privateKeyToAccount } from "viem/accounts";
const account = privateKeyToAccount(process.env.PRIVATE_KEY);
const pay = wrapFetchWithPayment(fetch, account);
const res = await pay("https://dns.use.x402atlas.com/txt", {
method: "GET",
});
