/arbys/categoriesapiKey1 credit/requestList Arby's menu categories
Returns Arby's US menu's top-level categories -- Slow Roasted Beef, Crispy Juicy Chicken, Meals, Sides & Snacks, Beverages, Desserts, Kids Menu and others. Each entry's slug is the value GET /arbys/menu takes. store_id (optional, default 0) selects which pricing snapshot categories' item counts are read from; the default 0 is Arby's own reference catalog and carries no prices at all -- pass a store_id you already know (for example one you have seen on arbys.com after picking a location) to price GET /arbys/menu's items against a specific store. There is no location-lookup endpoint in this family.
