Check if a domain name is available for registration by querying RDAP and DNS — pass a bare name (e.g. mybrand) to sweep it across 10 popular TLDs simultaneously, or a full domain (e.g. mybrand.com) to check that single domain — returns registration status, expiry date if registered, and available/taken TLD lists so agents can find the best domain for a brand or project.

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://netintel.dev/domain-availability/check", { method: "GET" });
console.log(await res.json());
