# Authentication

> Learn how to authenticate using API keys

# Authentication

The Scenext API uses Bearer Token authentication. You need to include your API key in the Header of each API request.

## Getting API Key

1. Log in to [scenext.cn](https://scenext.cn)
2. Go to your personal center
3. Find "API Keys Management"
4. Click "Create API Key"
5. Copy and save your API key

<Warning>
  Please keep your API key safe and do not expose it in client-side code.
</Warning>

## Using API Key

Include the following Header in each API request:

```http theme={null}
Authorization: Bearer YOUR_API_KEY
Content-Type: application/json
```

## Examples

### Python

```python theme={null}
import requests

headers = {
    "Authorization": "Bearer YOUR_API_KEY",
    "Content-Type": "application/json"
}

response = requests.post(
    "https://api.scenext.cn/api/gen_video",
    headers=headers,
    json=your_data
)
```

### JavaScript

```javascript theme={null}
const headers = {
    'Authorization': 'Bearer YOUR_API_KEY',
    'Content-Type': 'application/json'
};

fetch('https://api.scenext.cn/api/gen_video', {
    method: 'POST',
    headers: headers,
    body: JSON.stringify(your_data)
});
```

### cURL

```bash theme={null}
curl -X POST https://api.scenext.cn/api/gen_video \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"question": "Question", "answer": "Reference answer"}'
```

## Error Handling

If authentication fails, the API will return a 401 status code:

```json theme={null}
{
    "status": "error",
    "data": {
        "messages": "Unauthorized: Invalid API key"
    }
}
```

Make sure your API key is valid and correctly formatted.
