Lookproof

Check a pasted DNS zone file (RFC 1035 master format, up to 64 KiB) with $ORIGIN and $TTL: unreadable lines, SOA and NS at the apex, CNAME at the apex or beside other data, duplicates, mixed TTLs in a set, out-of-zone names, NS/MX targets without addresses and SOA timers. Offline. Use when an agent edits a zone before loading it. Input: {"zone": "$TTL 3600\n@ IN SOA ...", "origin": "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/zone-lint", { method: "POST" });
console.log(await res.json());
