import requests

resp = requests.get(
    "https://v1.apizero.cn/api/icp",

    "domain": "baidu.com",
    "key": "YOUR_API_KEY",
},
    timeout=15,
)
resp.raise_for_status()
print(resp.json())

// Node.js 18+ / 浏览器原生 fetch
const params = new URLSearchParams({
  "domain": "baidu.com",
  "key": "YOUR_API_KEY",

const res = await fetch(`https://v1.apizero.cn/api/icp?${params}`);
if (!res.ok) throw new Error(`HTTP ${res.status}`);
const data = await res.json();
console.log(data);
