# Seedance 2.0 Token 计费

> 使用 doubao-seedance-2-0 系列模型提交并查询按 token 计费的视频任务

使用 `doubao-seedance-2-0` 或 `doubao-seedance-2-0-fast` 提交视频生成任务。接口兼容 OpenAI Video API 格式，按输出 token 据实计费，任务完成后自动差额结算。

<RequestExample>
  ```bash 文生视频 1080p theme={null}
  curl -X POST https://gogogotoken.com/v1/video/generations \
    -H "Authorization: Bearer YOUR_API_KEY" \
    -H "Content-Type: application/json" \
    -d '{
      "model": "doubao-seedance-2-0",
      "prompt": "a premium smartwatch rotating on a clean studio pedestal, soft product lighting, slow camera push-in",
      "seconds": "5",
      "size": "1080x1920"
    }'
  ```

  ```bash 首帧图生视频 720p theme={null}
  curl -X POST https://gogogotoken.com/v1/video/generations \
    -H "Authorization: Bearer YOUR_API_KEY" \
    -H "Content-Type: application/json" \
    -d '{
      "model": "doubao-seedance-2-0-fast",
      "prompt": "turn the product image into a polished product showcase video with slow camera movement",
      "seconds": "5",
      "size": "720x1280",
      "first_frame_image": "data:image/png;base64,<BASE64_IMAGE>"
    }'
  ```
</RequestExample>

<ResponseExample>
  ```json 200 theme={null}
  {
    "id": "task_1234567890",
    "object": "video",
    "model": "doubao-seedance-2-0",
    "status": "queued",
    "progress": 0
  }
  ```

  ```json completed theme={null}
  {
    "id": "task_1234567890",
    "object": "video",
    "model": "doubao-seedance-2-0",
    "status": "completed",
    "progress": 100,
    "output": {
      "video_url": "https://assets.example.com/generated-video.mp4"
    },
    "usage": {
      "total_tokens": 108900,
      "completion_tokens": 108900
    }
  }
  ```
</ResponseExample>

## 查询任务状态

```bash theme={null}
curl https://gogogotoken.com/v1/video/generations/task_1234567890 \
  -H "Authorization: Bearer YOUR_API_KEY"
```

<Note>
  任务 `status` 变为 `"completed"` 后，系统会根据 `usage.completion_tokens` 和模型当时的分辨率/输入类型自动重算费用。可在控制台日志中查看实际扣费明细。
