lol, I think I saw this API recently for another game. It’s a GraphQL frontend right? They disabled introspection but their error messages will helpfully offer suggestions for misspelled field names

BTW, pro-tip when reversing APIs of popular services like this: use GitHub code search! Put some unique endpoint names into it and see what comes up. You’ll often find some kindred spirits who have hacked their own little API clients to do something you never even thought about, but which nevertheless helps you advance along your own quest…
