Fixed Fields

FieldRequiredTypeScopeDefaultDescription
custom_promptNOstringPrompt 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.
stepsNOinteger[1, +]30Sampling 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.
strengthNOfloat[0.1, 1.0]0.8The smaller the value, the closer it is to the original image.
scaleNOfloat[1, 20]7The degree to which the text description influences the output.
seedNOinteger[-1, +]0Random 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_heightNOinteger[0, +]1920Maximum output height. Resized to the specified dimensions as a fallback after the image expansion process.
max_widthNOinteger[0, +]1920Maximum output width. Resized to the specified dimensions as a fallback after the image expansion process.

Response

Response Field Handling Flow
  1. Handle Public Response Fields Parse and validate the Public Response Fields, checking the status code or response message to ensure the request is successful and error-free.
  2. Handle Business Response Fields If the Public Response Fields are valid and error-free, proceed with processing the business logic in the Business Response Fields.

Body

multipart/form-data
​
image
file

Original image.

​
mask
file

Mask image.

​
steps
integer

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.

Example:

"30"

​
strength
number

The smaller the value, the closer it is to the original image.

Example:

"0.8"

​
scale
integer

The degree to which the text description influences the output.

Example:

"7"

​
seed
integer

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.

Example:

"0"

​
top
number

Upward expansion ratio.

Example:

"0.1"

​
bottom
number

Downward expansion ratio.

Example:

"0.1"

​
left
number

Leftward expansion ratio.

Example:

"0.1"

​
right
number

Rightward expansion ratio.

Example:

"0.1"

​
max_height
integer

Maximum output height. Resized to the specified dimensions as a fallback after the image expansion process.

Example:

"1920"

​
max_width
integer

Maximum output width. Resized to the specified dimensions as a fallback after the image expansion process.

Example:

"1920"
