 Base URL: `http://127.0.0.1:8642`
 
-### 认证

-除 `/health` 外，所有接口支持 Bearer Token 认证（如果服务端配置了 `key`）：
+All endpoints except `/health` support Bearer Token authentication (if `key` is configured on the server):
 
 ```
 Authorization: Bearer <your-api-key>
 ```
 
-未配置 key 时所有请求放行。
+When no key is configured, all requests are allowed without authentication.
