Header

Field	Required	Type	Description
ailabapi-api-key	YES	string	Application API KEY. Get API KEY

Body

Fixed Fields

Field	Required	Type	Scope	Default	Description
custom_prompt	NO	string			Prompt Content (English only). Please limit the prompt content to 100 English words or fewer. Any content beyond this limit may have minimal impact on the generated result. Use standard vocabulary to avoid failing the review process.
steps	NO	integer	[1, +]	30	Sampling steps determine the level of detail in the generated image. A higher value may result in better quality, but it will significantly increase the processing time.
strength	NO	float	[0.1, 1.0]	0.8	The smaller the value, the closer it is to the original image.
scale	NO	float	[1, 20]	7	The degree to which the text description influences the output.
seed	NO	integer	[-1, +]	0	Random seed, used as the basis for determining the initial state of the diffusion process. It must be a non-negative number (-1 represents a random seed). If the random seed is the same positive integer and all other parameters are identical, the generated image will most likely be consistent.
max_height	NO	integer	[0, +]	1920	Maximum output height. Resized to the specified dimensions as a fallback after the image expansion process.
max_width	NO	integer	[0, +]	1920	Maximum output width. Resized to the specified dimensions as a fallback after the image expansion process.

Non-Mask Expanded Image

Field	Required	Type	Scope	Default	Example	Description
image	YES	file				Original image.
top	NO	float	[0, 1.0]	0.1		Upward expansion ratio.
bottom	NO	float	[0, 1.0]	0.1		Downward expansion ratio.
left	NO	float	[0, 1.0]	0.1		Leftward expansion ratio.
right	NO	float	[0, 1.0]	0.1		Rightward expansion ratio.

Mask Expanded Image

Field	Required	Type	Example	Description
image	YES	file		Original image.
mask	YES	file		Mask image.
