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.

# you can also pass username, password to the WebUIApi constructor.

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)

This is an unofficial implementation to use the api of promptgen. Before installing the extension you have to check if you already have an extension called Promptgen. If so, you need to uninstall it. Once uninstalled you can install it in two ways:
cd stable-diffusion-webui/extensions
git clone -b api-implementation https://github.com/davidmartinrius/stable-diffusion-webui-promptgen.git
Once installed:
api = webuiapi.WebUIApi()
result = api.list_prompt_gen_models()
print("list of models")
print(result)
# you will get something like this:
#['AUTOMATIC/promptgen-lexart', 'AUTOMATIC/promptgen-majinai-safe', 'AUTOMATIC/promptgen-majinai-unsafe']
text = "a box"
To create a prompt from a text:
# by default model_name is "AUTOMATIC/promptgen-lexart"
result = api.prompt_gen(text=text)
# Using a different model
result = api.prompt_gen(text=text, model_name="AUTOMATIC/promptgen-majinai-unsafe")
#Complete usage
result = api.prompt_gen(
text=text,
model_name="AUTOMATIC/promptgen-majinai-unsafe",
