webuiapi 0.9.16

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=username:password is set on webui.
# username, password are not protected and can be derived easily if the communication channel is not encrypted.
# you can also pass username, password to the WebUIApi constructor.
api.set_auth('username', 'password')

txt2img

result1 = api.txt2img(prompt="cute squirrel",
                    negative_prompt="ugly, out of frame",
                    seed=1003,

img2img inpainting

from PIL import Image, ImageDraw

mask = Image.new('RGB', result2.image.size, color = 'black')
# mask = result2.image.copy()
draw = ImageDraw.Draw(mask)
draw.ellipse((210,150,310,250), fill='white')

Async API support

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

result = await api.txt2img(prompt="cute kitten",
                    seed=1001,
                    use_async=True
                    )
result.image

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/Z Plot script:

(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

Prompt generator API by David Martin Rius:

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:

1. From the user interface

2. From the command line

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",
        batch_count= 1,
        batch_size=10,
        min_length=20,
        max_length=150,
        num_beams=1,
        temperature=1,
        repetition_penalty=1,
        length_preference=1,
        sampling_mode="Top K",
        top_k=12,
        top_p=0.15
    )

# result is a list of prompts. You can iterate the list or just get the first result like this: result[0]

TIPS for using Flux David Martin Rius:

In both cases, it is needed cfg_scale = 1, sampler_name = "Euler", scheduler = "Simple" and in txt2img enable_hr=False

For txt2img

import webuiapi

result1 = api.txt2img(prompt="cute squirrel",
                    negative_prompt="ugly, out of frame",
                    seed=-1,
                    styles=["anime"],
                    cfg_scale=1,
                    steps=20,
                    enable_hr=False,
