xyz域名有用吗

import requests

def check_xyz_domain_availability(domain):
    url = f"https://dns.google/resolve?name={domain}&type=A"
    response = requests.get(url)
    if response.status_code == 200:
        data = response.json()
        if 'Answer' in data and len(data['Answer']) > 0:
            return False  # 域名已被注册
        else:
            return True   # 域名可用
    else:
        return None   # 请求失败

# 使用示例
domain_to_check = "example.xyz"
availability = check_xyz_domain_availability(domain_to_check)
if availability is True:
    print(f"{domain_to_check} 是可用的！")
elif availability is False:
    print(f"{domain_to_check} 已被注册。")
else:
    print("无法检查域名的可用性。")
