# 若没有配置环境变量，请用百炼API Key将下行替换为：api_key="sk-xxx"
# 获取API Key：https://help.aliyun.com/zh/model-studio/get-api-key

media = [{'type': 'video_url', 'url': 'https://help-static-aliyun-doc.aliyuncs.com/file-manage-files/zh-CN/20250717/pvegot/input_video_01.mp4'}, {'type': 'audio_url', 'url': 'https://help-static-aliyun-doc.aliyuncs.com/file-manage-files/zh-CN/20250717/aumwir/stella2-%E6%9C%89%E5%A3%B0%E4%B9%A67.wav'}]

TTS 文本驱动

传入视频和 TTS 文本，由模型合成语音并生成对口型视频。

    -d '{
    "model": "pixverse/pixverse-lipsync",

            }
        ]
    },
    "parameters": {
        "watermark": true
    }
}'

查询任务结果

将{task_id}完整替换为上一步接口返回的task_id的值。task_id查询有效期为24小时，并请将{WorkspaceId}替换为真实的业务空间ID。

curl -X GET https://{WorkspaceId}.cn-beijing.maas.aliyuncs.com/api/v1/tasks/{task_id} \
--header "Authorization: Bearer $DASHSCOPE_API_KEY"

任务执行成功

{
    "request_id": "ddf8140e-67c6-9e70-8953-xxxxxx",
    "output": {
        "task_id": "1acb9d0c-7a63-4ff6-a198-xxxxxx",
        "task_status": "SUCCEEDED",
        "submit_time": "2026-07-15 17:01:49.352",
        "scheduled_time": "2026-07-15 17:01:49.398",
        "end_time": "2026-07-15 17:02:29.724",
        "video_url": "https://media.pixverseai.cn/xxxx.mp4"
    },
    "usage": {
        "duration": 7,
        "size": "1080*1920",
        "fps": 24,
        "video_count": 1,
        "SR": ""
    }
}

任务执行失败

若任务执行失败，task_status将置为 FAILED，并提供错误码和信息。请参见错误码进行解决。

{
    "request_id": "e5d70b02-ebd3-98ce-9fe8-759d7d7b107d",
    "output": {
        "task_id": "86ecf553-d340-4e21-af6e-a0c6a421c010",
        "task_status": "FAILED",
        "code": "InvalidParameter",
        "message": "Invalid field type or value. Please verify your input data."
    }
}

任务查询过期

task_id查询有效期为 24 小时，超时后将无法查询，返回以下报错信息。

{
    "request_id": "a4de7c32-7057-9f82-8581-xxxxxx",
    "output": {
        "task_id": "502a00b1-19d9-4839-a82f-xxxxxx",
        "task_status": "UNKNOWN"
    }
}
