Request body

11 properties · 2 required · 1 $defs

property	type	description	constraints
prompt*	string	Text prompt for image generation.
image_urls*	string[]	URL(s) of the condition image(s) for image-to-image generation. Supports up to 4 URLs for multi-image references.
output_format	enum	Output image format.	jpeg \| png · default: "jpeg"
guidance_scale	number	Classifier-free guidance scale. Higher values make the model follow the prompt more closely.	1 ≤ n ≤ 10 · default: 1.5
seed	integer	Random seed for reproducibility. The same seed with the same prompt will produce the same image.	nullable
num_inference_steps	integer	Number of diffusion denoising steps. More steps generally produce higher quality images.	10 ≤ n ≤ 100 · default: 30
image_size	ImageSize \| enum	Output image size.	default: "square_hd"
enable_prompt_expansion	boolean	If True, the prompt will be enhanced using an LLM for more detailed and higher quality results.	default: false
sync_mode	boolean	If True, the image will be returned as a base64 data URI instead of a URL.	default: false
enable_safety_checker	boolean	Enable NSFW safety checking on the generated images. Disabling it requires account authorization; unauthorized requests are always checked, and images flagged as unsafe are returned as black images.	default: true
num_images	integer	Number of images to generate.	1 ≤ n ≤ 4 · default: 1
