curl -X POST https://runapi.ai/v1/tools/search \
  -H Authorization:\ Bearer\ YOUR_API_TOKEN \
  -H Content-Type:\ application/json \
  -d \{\"query\":\"DeepSeek\ V4\ release\",\"count\":5,\"ori_question\":null,\"localization\":\"203.0.113.7\",\"need_content\":true\}
```

### javascript

```javascript
const response = await fetch("https://runapi.ai/v1/tools/search", {
  method: "POST",
  headers: {
  "Authorization": "Bearer YOUR_API_TOKEN",
  "Content-Type": "application/json"
},
  body: JSON.stringify({
  "query": "DeepSeek V4 release",
  "count": 5,
  "ori_question": null,
  "localization": "203.0.113.7",
  "need_content": true
})
});
if (!response.ok) throw new Error(`HTTP ${response.status}`);
const data = await response.json();
console.log(data);
```

### python

#### Install

```bash
pip install requests
```

```python
import requests

response = requests.post(
    "https://runapi.ai/v1/tools/search",
    headers={"Authorization": "Bearer YOUR_API_TOKEN", "Content-Type": "application/json"},
    json={"query": "DeepSeek V4 release", "count": 5, "ori_question": None, "localization": "203.0.113.7", "need_content": True}
