Cloudflare DNS 更新（DDNS） API 接入文档cf-dns

需要登录 API Key（涉及用户 Token，不开放匿名访问）。

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 -X POST "https://v1.apizero.cn/api/cf-dns" \
  -H "X-Api-Key: YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
  "domain": "example.com",
  "host": "home",
  "ip": "<ip>",
  "token": "<token>",
  "type": "<type>",
  "ttl": "<ttl>",
  "proxied": "<proxied>"
}'
