How do you get control net preprocess and use it?

[dbokser]

ControlNet API documentation shows how to get the available models for control net but there's not a lot of info on how to get the preprocessors and how to use them. Any info on how to access this functionality?

Thanks, but I was looking more at how the preprocessors are accessible through the web API. As far as I can see, there are only 4 available commands
POST /controlnet/txt2img
POST /controlnet/img2img
GET /controlnet/model_list
POST /controlnet/detect

I'm a bit late, but for anyone else looking for the same problem - POST /controlnet/detect is the one you need. More info here https://github.com/Mikubill/sd-webui-controlnet/wiki/API#integrating-sdapiv12img
