Lookproof

Check a zone's SOA record through public resolvers: primary server, contact name, serial (YYYYMMDDnn or counter), refresh, retry, expire and negative caching TTL against RFC 1912 and RFC 2308. Use when an agent must explain zone transfer timers or why a deleted name keeps answering NXDOMAIN. Input: ?domain=example.com.

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.lookproof.dev/v1/dns/soa", { method: "GET" });
console.log(await res.json());
