调用前准备

• 提供一个公开图片 URL 或一个 base64 图片字符串
• 建议从 model_name: kling-v2-master 开始，以发起一个最简的现代请求
• 首次请求尽量保持简单：一张输入图片、一个 prompt、不使用尾帧、不使用运动遮罩

​

任务流程

1. 提交图片生成视频请求

   创建任务并保存返回的 Kling task_id。

2. 轮询任务

   继续参考 单项查询 跟踪任务状态，直到输出准备就绪。

3. 保存结果

   如果你需要在提供商交付 URL 失效后继续保留资源，请持久化保存最终产物。

2026-03-12 的实时验证已确认，基于 URL 的 kling-v2-master 请求可被接受，并返回 task_status: submitted。
