View Source SpeedrunClient.Categories (srex v0.1.0)

Categories are the different rulesets for speedruns. Categories are either per-game or per-level (if the game uses individual levels), both can be accessed via this resource.

This resource is meant to perform ID-based lookups. That's why there is no GET /categories to get a flat list of all categories across all games. If you want to get the categories for a game, use GET /v1/games/{gameid}/categories.
