To close this one off, I know documentation is hard (in fact, I hate documentation myself, go figure!)
That said, even if you just give me the list of every parameter that's valid at an API endpoint, that already saves me soooo much time. I can test the output with something like http-prompt in such a situation and get the rest from it myself, but at the very least provide this basic thing.
It's like Twitter but you can like host it yourself n crap. This instance will probably contain high dosages of weeb. TO GET APPROVED, READ THE ABOUT PAGE!
