Wow, great! And here I've found this exactly ~1 day after wasting time trying to implement something similar for my study planning purposes. :) [Shameless plug: https://jkozera.github.io/oudashboard/ - you can load the calendar from https://jkozera.github.io/oudashboard/sample.ics instead of fetching one from the OU, no sign up is required]
Given the above, I would love to integrate these calendars with some Zenkit API instead. I see a 'Generate new API key' option in settings, but cannot find any API docs anywhere. Is API access going to be free? Please at least allow it for students. :)
