使用此端点可调用由 CometAPI 提供的兼容 O1 的 Kling Omni 工作流，包括文生视频和首帧图片参考生成。

有关完整的提供商参数参考，请参阅 Kling Omni 视频文档。

选择输入模式

文生视频：发送 prompt、mode、aspect_ratio 和 duration
首帧图片参考：添加包含 image_url 和 type: first_frame 的 image_list 项，然后在 prompt 中使用 <<<image_1>>> 引用该图片
带水印输出：当你需要在查询响应中获得带水印的视频 URL 时，添加 watermark_info.enabled: true
model ID：省略 model_name 以使用该路由默认值，或发送已测试的 Omni Video model ID，例如 kling-video-o1 或 kling-v3-omni

时长和宽高比

设置	支持的值	默认值	边界行为
文本或首帧视频的 `duration`	`"5"`、`"10"`	`"5"`	将该值作为字符串发送，并使用两种固定生成时长之一。
`aspect_ratio`	`16:9`, `9:16`, `1:1`	`16:9`	当没有首帧图片控制画面时为必填。
`mode`	`std`, `pro`	路由默认值	标准生成请发送 `std`，只有在你选择的模型支持更高质量模式时才发送 `pro`。

Kling Omni 不提供精确的 size 字段。请将 aspect_ratio 视为画面形状请求；16:9 的文生视频请求可渲染为全高清 1920x1080。
