API client for AUTOMATIC1111/stable-diffusion-webui
Supports txt2img, img2img, extra-single-image, extra-batch-images API calls.
API support have to be enabled from webui. Add --api when running webui. It's explained here.
You can use --api-auth user1:pass1,user2:pass2 option to enable authentication for api access. (Since it's basic http authentication the password is transmitted in cleartext)
API calls are (almost) direct translation from http://127.0.0.1:7860/docs as of 2022/11/21.
pip install webuiapi
webuiapi_demo.ipynb contains example code with original images. Images are compressed as jpeg in this document.

# optionally set username, password when --api-auth=username:password is set on webui.

txt2img, img2img, extra_single_image, extra_batch_images support async api call with use_async=True parameter. You need asyncio, aiohttp packages installed.

Scripts from AUTOMATIC1111's Web UI are supported, but there aren't official models that define a script's interface.
To find out the list of arguments that are accepted by a particular script look up the associated python file from
AUTOMATIC1111's repo scripts/[script_name].py. Search for its run(p, **args) function and the arguments that come
after 'p' is the list of accepted arguments
(scripts/xyz_grid.py file from AUTOMATIC1111's repo)
def run(self, p, x_type, x_values, y_type, y_values, z_type, z_values, draw_legend, include_lone_images, include_sub_grids, no_fixed_seeds, margin_size):
...
List of accepted arguments:
- x_type: Index of the axis for X axis. Indexes start from [0: Nothing]
- x_values: String of comma-separated values for the X axis
- y_type: Index of the axis type for Y axis. As the X axis, indexes start from [0: Nothing]
- y_values: String of comma-separated values for the Y axis
- z_type: Index of the axis type for Z axis. As the X axis, indexes start from [0: Nothing]
- z_values: String of comma-separated values for the Z axis
- draw_legend: "True" or "False". IMPORTANT: It needs to be a string and not a Boolean value
- include_lone_images: "True" or "False". IMPORTANT: It needs to be a string and not a Boolean value
- include_sub_grids: "True" or "False". IMPORTANT: It needs to be a string and not a Boolean value
- no_fixed_seeds: "True" or "False". IMPORTANT: It needs to be a string and not a Boolean value
- margin_size: int value
