Reasons to use the API

1. Automated Processes. You can create a script that generates images while you do other things. The script can randomize parameters to achieve different results. Or the script could go through a list of prompts and generates images for each prompt.

2. Building a client app. Build and monetize an app that will generate images for other users.

Getting Started

When you start Automatic1111, make sure to include the --api option. For example:

stable-diffusion-webui/ --listen --xformers --api

All endpoints are located at: /sdapi/v1/*. For example, http://localhost:7860/sdapi/v1/txt2img.

The official api spec can be seen by going to /docs on your server, but it is very basic.
