Usage notes

Always include a non-empty top-level prompt, including when using multi_prompt. Keep it within 2,500 characters; longer prompts are truncated.
For custom shots, set multi_shots to true and provide 1–6 multi_prompt objects. Each object needs prompt (at most 512 characters) and duration (a positive integer from 1 to 15 seconds).
Custom-shot durations are summed for generation and billing; the top-level duration does not override that sum. With multi_shots enabled and no custom shots, the top-level duration is retained.
Native audio uses sound: on or off and defaults to on.
elements contains Kling element IDs as decimal strings. Each ID must belong to the account making the request; arbitrary provider IDs are rejected.
