UvA Timetable API (MyTimetable tenancy)
The university timetable at rooster.uva.nl exposes a JSON API under /api/ that answers 401 with a structured error to unauthenticated callers, so the surface is real and gated behind institutional sign-in. The host CNAMEs to uva.hosting.eveoh.nl — it is Eveoh's MyTimetable product, not UvA engineering. Recorded because a timetable API is one of the classes a university genuinely has, and because it is the only one here.
