NavigaTUM
Search and navigation API for TUM rooms, buildings and places — a Rust service over MeiliSearch, fully unauthenticated, documented with an OpenAPI 3 contract served live at https://nav.tum.de/api/openapi.json. Twelve operations across search, locations, maps, calendar, feedback and status. GET /api/status returns the exact deployed commit alongside its health, a build-provenance practice almost nothing else in this cohort does. Also publishes a .well-known/security.txt. The six OpenAPI files below are one contract split by tag by refine-openapis, not six APIs; they were repaired on 2026-08-19 after that split had stamped them with eat-api's title and eat-api's GitHub Pages servers block.
