## Request body

- Qwen21ImageToImageRequest
  - `prompt` string, required: The prompt describing the result you want. When mask_url is supplied, describe what should be generated inside the white area of the mask.
  - `images_list` string[], required: Reference images, 1 to 10 URLs. Order matters when the prompt refers to 'the first image', 'the second image', etc.
  - `mask_url` string, uri, nullable: Inpainting mask (white = area to change, black = kept unchanged) that switches the request into local-edit mode. Must be used with exactly one reference image.
  - `aspect_ratio` 'auto' | '1:1' | '4:3' | '3:4' | '3:2' | '2:3' | '16:9' | '9:16' | '21:9' | '9:21', nullable: Output image aspect ratio. Defaults to the first reference image's ratio. Ignored in local-edit mode.
  - `resolution` '1K' | '2K', nullable: Output resolution tier. 2K produces four times the pixels and takes longer.

  - `output_format` 'jpeg' | 'png' | 'webp', nullable: Output image format. JPEG has no alpha channel and cannot be combined with a transparent background.
  - `enhance_prompt` boolean, nullable: Rewrites the prompt into a fuller scene description before generating, improving quality.
