imagestring | string[]conditionalRequired for image workflows: one URL string for image-to-image, interactive edit, or layer decomposition; an array of 2–10 URLs for multi-image fusion. Image-to-image supports jpeg/png/webp/bmp/tiff/gif/heic/heif, aspect ratio 1:16–16:1, up to 30 MB.
sizestringoptionalGeneration: 1K, 1.5K, 2K (default), or pixel values such as 2048x1024. Layer decomposition: 1K, 1.5K, 2K, or auto (default, preserves input size); pixel values are not supported for layers.
output_formatenumoptionalpng or jpeg; defaults to jpeg.
response_formatenumoptionalurl or b64_json; defaults to url. Download URLs are valid for 24 hours.
backgroundenumoptionaltransparent or opaque (default). Transparent backgrounds are for image-to-image with an alpha-channel input; output defaults to png. Not listed in the text-to-image, multi-image, interactive-edit, or layer-decomposition workflow schemas.
