eat-api — Munich Student Canteen Menus

Static JSON API for Munich student canteen menus, prices, dish labels and opening hours, regenerated on a schedule and served as flat files from GitHub Pages. Two OpenAPI files below are one contract split by tag; both were re-titled on 2026-08-19 after refine-openapis had labelled them "eat-api calendar API" and conflated them with NavigaTUM.
