Need API Document

I found these API keywords in server.py.Would you add some use case of these?
BTW 1.the API "/prompt" will generate pic file in the output folder,is there a method to delete the file after I download the file?
BTW 2.When I use img2img with API,I have to upload image file to input folder first.Do I have to write my own file uploader program?
