+
+### Python
+
+```python
+import requests
+
+BASE_URL = "http://127.0.0.1:5031"
+
+# 获取会话列表
+sessions = requests.get(f"{BASE_URL}/api/v1/sessions").json()

+
+# 获取消息

+    "talker": "wxid_xxx",
+    "limit": 100,
+    "chatlab": 1
+}).json()
+print(messages)
+```
+
+### JavaScript / Node.js
+
+```javascript
+const BASE_URL = "http://127.0.0.1:5031";
+
+// 获取会话列表
+const sessions = await fetch(`${BASE_URL}/api/v1/sessions`).then(r => r.json());
+console.log(sessions);
+
+// 获取消息（ChatLab 格式）
+const messages = await fetch(`${BASE_URL}/api/v1/messages?talker=wxid_xxx&chatlab=1`)
+  .then(r => r.json());
+console.log(messages);
+```
+
+---
+
+## 注意事项
+
+1. API 仅监听本地地址 `127.0.0.1`，不对外网开放
+2. 需要先连接数据库才能查询数据
+3. 时间参数格式为 `YYYYMMDD`（如 20260205）
+4. 支持 CORS，可从浏览器前端直接调用
