DNS 劫持检测 API 接入文档dns-check

匿名 QPS=2、日 50 次；登录后 QPS=5、日 200 次。一次请求会向 4 家 DoH 各发 2 条查询（A + AAAA），共 8 个并发 HTTPS 请求。

获取 API Key：登录 https://apizero.cn/account/keys

以下 5 种语言示例都是可直接运行的，只需把 YOUR_API_KEY 替换为实际 Key。

curl "https://v1.apizero.cn/api/dns-check?domain=%3Cdomain%3E&key=YOUR_API_KEY"

import requests

resp = requests.get(
    "https://v1.apizero.cn/api/dns-check",
    params={
    "domain": "<domain>",
    "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": "<domain>",
  "key": "YOUR_API_KEY",
});

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

• 1.0.0(2026-05-06)
  • 首次发布：4 家 DoH 并发（AliDNS / DNSPod / 360 / Cloudflare）
  • 每家同时查询 A + AAAA + CNAME（共 8 个并发 HTTPS 请求）
  • 智能风险分级：safe / safe_with_geodns / suspicious / hijack_likely / unknown
  • 比源码增强：CNAME 链路 / IPv6 / TTL / 各服务器独立状态码
