Easy SDWebUI API - Easy API for SDWebUI, forked from mix1009/sdwebuiapi

easyai-sdwebui-api

API client for AUTOMATIC1111/stable-diffusion-webui

Tested on AUTOMATIC1111/stable-diffusion-webui v1.2.x/v1.4.x and Mikubill/sd-webui-controlnet v1.1.232

• 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 easyai-sdwebui-api

Usage

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

create API client

import easyai

# create API client
api = easyai.EasyAPI()

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

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

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

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

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

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
