Request body

5 properties · 1 required · 0 $defs

property	type	description	constraints
prompt*	string	The text prompt used to generate or edit the image.	length ≥ 1
aspect_ratio	string	Any custom output aspect ratio as "width:height", for example "16:9", "5:4", or "1920:1200". Common presets are "21:9", "16:9", "4:3", "3:2", "1:1", "2:3", "3:4", "9:16", "9:21". The ratio must be between 1:16 and 16:1, the range Muse supports. Only the ratio is used: Muse renders it at its own fixed resolution of roughly 2.5 megapixels, so "1920:1200" and "960:600" both return the same 1920x1200 image. If omitted, Muse chooses the output dimensions automatically.	nullable
sync_mode	boolean	If `True`, the image is returned as a data URI and is not persisted in the request history.	default: false
num_images	integer	The number of images to generate.	1 ≤ n ≤ 10 · default: 1
output_format	enum	The format of the generated image.	jpeg \| png \| webp · default: "webp"
