webuiapi 0.1.1

Python API client for AUTOMATIC1111/stable-diffusion-webui

sdwebuiapi

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.

Install

pip install webuiapi

Usage

webuiapi_demo.ipynb contains example code with original images. Images are compressed as jpeg in this document.

create API client

import webuiapi

# create API client
api = webuiapi.WebUIApi()

# create API client with custom host, port
#api = webuiapi.WebUIApi(host='127.0.0.1', port=7860)

# create API client with custom host, port and https
#api = webuiapi.WebUIApi(host='webui.example.com', port=443, use_https=True)

# create API client with default sampler, steps.
#api = webuiapi.WebUIApi(sampler='Euler a', steps=20)

# optionally set username, password when --api-auth is set on webui.
api.set_auth('username', 'password')

Scripts support

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

Example for X/Y Plot script:

(scripts/xy_grid.py file from AUTOMATIC1111's repo)

def run(self, p, x_type, x_values, y_type, y_values, draw_legend, include_lone_images, no_fixed_seeds):
    ...

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
• 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
• no_fixed_seeds: "True" or "False". IMPORTANT: It needs to be a string and not a Boolean value

Configuration APIs

# return map of current options
options = api.get_options()

# change sd model
options = {}

api.set_options(options)

# when calling set_options, do not pass all options returned by get_options().
# it makes webui unusable (2022/11/21).

# get available sd models
api.get_sd_models()

# misc get apis
api.get_samplers()
api.get_cmd_flags()

Utility methods

# save current model name
old_model = api.util_get_current_model()

# get list of available models
models = api.util_get_model_names()

# set model (use exact name)
api.util_set_model(models[0])

# set model (find closest match)
