使用此端点可根据 Prompt 创建一个 Kling 文本生成视频任务。它会启动一个异步作业，而不是立即返回已完成的视频。

​
首个可用请求

  • 先发送一个简短的 Prompt
  • 仅在基础流程跑通后再添加 aspect_ratio、duration 或 mode
  • 如果你希望使用推送交付而不是纯轮询，请设置 callback_url

​
任务流程

1

提交生成请求

通过此端点创建任务，并保存返回的 Kling task id。
2

轮询任务状态

通过 单项查询 检查进度，直到任务进入终态。
3

持久化结果

当 Kling 返回已完成资源的元数据后，如果你需要长期保留，请将结果转存到你自己的存储中。
有关完整的参数矩阵和模型轨道详情，请参阅 Kling 官方文档。
