Input parameters

Name	Type	Required	Description
`prompt`	string	required	The prompt that describes the image content, style and composition you want to generate. Required. Any language is supported, up to 5000 characters; longer input returns 422.
`aspect_ratio`	string	optional	The output aspect ratio. Default `1:1`. The actual pixel size also depends on `resolution` — see the aspect ratio table above for the exact dimensions of each combination. Values: `1:1`, `4:3`, `3:4`, `3:2`, `2:3`, `16:9`, `9:16`, `21:9`, `9:21` Default: `1:1`
`resolution`	string	optional	The output resolution tier. `1K` is the faster option at roughly 7-12 seconds; `2K` produces four times the pixels and takes roughly 30-55 seconds. Only `1K` and `2K` are accepted — any other value, including `4K`, returns 422. Values: `1K`, `2K` Default: `1K`
`background`	string	optional	Background type. transparent outputs a PNG or WebP with a real alpha channel and cannot be used with JPEG. When using transparent, describe only the subject — prompts that mention a background, scene, surface, etc. may produce a non-transparent result. Values: `opaque`, `transparent` Default: `opaque`
`output_format`	string	optional	The output image format. `png` (default) and `webp` both carry an alpha channel and can be used with `background: transparent`. `jpeg` has no alpha channel and cannot be combined with a transparent background. Values: `png`, `webp`, `jpeg` Default: `png`
`enhance_prompt`	boolean	optional	Rewrites the prompt into a fuller scene description before generating, which noticeably improves quality. Enabled by default (also when the parameter is omitted); pass false to turn it off. Default: `True`
`seed`	integer	optional	The random seed. Omit it to generate with a random seed; the seed actually used is returned with the result. Passing the same seed together with the same prompt and parameters reproduces the same image within the same service version.
`nsfw_checker`	boolean	optional	Defaults to false. You can set it to false based on your needs. If set to false, our content filtering will be disabled, and all results will be returned directly by the model itself. Note: There is no guarantee that everything can be filtered out; if you are not satisfied with the results, you will need to make your own arrangements.
