Generate a sound effect for a previously generated spritesheet animation. Pass, as `spritesheet_video_url`, the `video_url` you received from `animateSprite`, `animateSpriteKeyframes`, `transferMotion`, or `editSpritesheet` - it must belong to a spritesheet you generated within the last 7 days; arbitrary external videos are not accepted. Spritesheets generated with the hydra model already come with `audio_b64`, so only call this for forge / forge-pixel output or to replace hydra's sound. Optionally add a `prompt` describing the sound you want. The job result is the URL of the generated audio file only; no video is returned. The audio is also attached to the spritesheet, so it appears as `audio_b64` in listGenerations (type spritesheet), where the spritesheet keeps the `request_id` it was generated with. Pass an optional `request_id` to make this call idempotent and to find its job again; it must not be one you already used for another generation. Async generation job: returns `{id, status}` - poll `getApiJob` (job and credit contract: see the server instructions). Credits: This endpoint consumes 3 credits per call.
