以下示例使用新版火山官方格式创建一个 4 秒、480p 的文生视频任务。

1. 创建任务

curl -X POST "https://www.dianlitoken.com/api/v3/contents/generations/tasks" \
  -H "Authorization: Bearer $DIANLI_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "doubao-seedance-2-0-260128",
    "content": [
      {"type": "text", "text": "晨雾中的森林，阳光穿过树梢，电影感运镜"}
    ],
    "resolution": "480p",
    "ratio": "16:9",
    "duration": 4,
    "generate_audio": true,
    "watermark": false
  }'

响应示例：

{
  "id": "task_xxx"
}

2. 查询任务

curl "https://www.dianlitoken.com/api/v3/contents/generations/tasks/task_xxx" \
  -H "Authorization: Bearer $DIANLI_API_KEY"

生成成功后，视频地址位于 content.video_url：

{
  "id": "task_xxx",
  "model": "doubao-seedance-2-0-260128",
  "status": "succeeded",
  "content": {
    "video_url": "https://example.com/result.mp4"
  },
  "resolution": "480p",
  "duration": 4,
  "ratio": "16:9",
  "usage": {
    "completion_tokens": 12345,
    "total_tokens": 12345
  },
  "updated_at": 1787535150
}

轮询间隔建议从 3～5 秒开始，并逐步退避。也可以传入 callback_url 接收任务状态通知，但客户端仍应保留查询接口作为补偿机制。处理中响应不保证包含 progress。
