Generate Kling v3 Video (background)

Submit a Kling v3 video generation job. Runs in the background.

Request body: Use GenerateKling3VideoRequest with:

  • prompt (required), start_image_url (required – starting image for image-to-video)
  • duration (3–15), aspect_ratio ("9:16" | "16:9" | "1:1")
  • multi_prompt, elements, generate_audio, shot_type, negative_prompt, cfg_scale

Send valid JSON (Content-Type: application/json). If the prompt contains newlines, they must be escaped in JSON (e.g. as \n). Using JSON.stringify() or your language's JSON encoder ensures valid encoding.
