💻 Integration Examples

Node.js

import fetch from 'node-fetch';

async function getWhoisServer(tld) {
  const url = 'https://raw.githubusercontent.com/simplebytes-com/whois-server-list/main/whois_servers.json';
  const servers = await fetch(url).then(r => r.json());
  return servers[tld.toLowerCase()];
}
