Lookproof

Evaluate a domain's CAA records (RFC 8659), climbing to parent names up to the registrable domain when the name has none: allowed issuers for normal and wildcard certificates, iodef, unknown critical tags and invalid values. Use when an agent must tell which certificate authorities may issue for a domain, or why a certificate request is refused because of CAA.

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/caa", { method: "GET" });
console.log(await res.json());
