`POST /tools/generate_ai_video`

## Request

- Base URL: `https://api.bannerbear.com/v5`
- URL: `https://api.bannerbear.com/v5/tools/generate_ai_video`
- Auth: HTTP bearer

Generate a video from a prompt or image with AI. Async — returns 202 with a pending job; poll GET /tool_jobs/{uid} until `status` is `completed` or `failed`.

## Request body

- object
  - `prompt` string, required: What happens in the clip — describe the subject, motion, camera and style
  - `model` 'seedance_1_lite' | 'seedance_2' | 'kling_2_5_turbo_pro' | 'veo_3_1_fast', required: AI credit cost varies by model, length and resolution
  - `duration` string: Each model offers some of these lengths — Kling 5 or 10, Veo 4, 6 or 8, Seedance any
  - `resolution` '480p' | '720p' | '1080p': Higher resolutions cost more per second — Kling's is fixed
  - `aspect_ratio` '16:9' | '9:16' | '1:1' | '4:3' | '3:4': Ignored when a starting image is given — the clip takes the image's shape
  - `image_url` string, uri: Optional — the clip begins from this frame and animates it
  - `audio` 'on' | 'off': Generated sound, on the models that can — Veo charges less without it
  - `metadata` string: Arbitrary metadata string stored with the tool run
