Lookproof

Convert a domain name between Unicode and punycode (A-labels) and check it against IDNA2008 and UTS 46: disallowed characters, bidi, context and hyphen rules, lengths, and mixed scripts in one label (homograph risk), per label. Offline. Use when an agent must register, compare or display an internationalised domain. Input: ?name=bücher.example.com.

Call it from code

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