There seems to be currently a problem with the docs.ninjastic.space site. (I tried different browsers and cleared cache and cookies, but the issue still persists on multiple browsers.)
Accessing
https://docs.ninjastic.space gives me (in Firefox as an example):
API docs have been down for ages because I lost the json files I used for that page.
The API is working as usual, just the docs aren't accessible because I didn't have the time to rewrite them. Also, I'm working on the new
beta.ninjastic.space which at one point will probably have its own improved API endpoint.
