Request body

7 properties · 0 required · 6 $defs

property	type	description	constraints
style	enum	A style for the generated image. Requires 'prompt'; not with 'image_url', 'vgl' or 'negative_prompt'.	Kodak Film \| Hard Flash \| Hazy Dreamy \| Rough Realism · nullable
seed	integer	Random seed for reproducibility, 0 to 2147483647.	0 ≤ n ≤ 2147483647 · default: 5555
image_url	string	A reference image (inspire mode). With 'prompt', VGL uses it as a visual reference for the prompt's scene and generates a new image of that scene, not the image. Alone, the VGL describes the image itself, so the result is a close variation of it. Not with 'vgl'.	nullable
vgl	Vgl	A VGL (Visual Generation Language) document: the structured JSON description of the scene. Alone, the model renders it as-is. With 'prompt', VGL changes it by the prompt (refine) and the result is rendered. Accepts what a previous request returned. Not with 'image_url' or 'style'.	nullable
aspect_ratio	enum	Aspect ratio of the image, at about one megapixel. Options: 1:1, 1:2, 1:3, 1:4, 1:5, 2:1, 2:3, 3:1, 3:2, 3:4, 4:1, 4:3, 4:5, 5:1, 5:4, 9:16, 9:21, 10:16, 16:9, 16:10, 21:9	1:1 \| 1:2 \| 1:3 \| 1:4 \| 1:5 \| 2:1 · +15 more · default: "1:1"
prompt	string	What to generate, in free-form text. It is expanded into a VGL, which is returned. With 'vgl', the change to make to it.	nullable
sync_mode	boolean	If true, returns the image directly in the response (increases latency).	default: false
