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')

txt2img

result1 = api.txt2img(prompt="cute squirrel",
                    negative_prompt="ugly, out of frame",

#                      steps=30,
                    )
# images contains the returned images (PIL images)
result1.images

# image is shorthand for images[0]
result1.image

# info contains text info about the api call

img2img inpainting

from PIL import Image, ImageDraw

mask = Image.new('RGB', result2.image.size, color = 'black')
# mask = result2.image.copy()

Configuration APIs

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

# change sd model

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
