NUSMods API (student-operated, not endorsed)

The only public machine-readable description of NUS course data that exists — module lists, module information, prerequisite trees, timetables and venue occupancy, published as an OpenAPI 3.0.1 document with academic-year path versioning. It is built and run by NUSModifications, a student organisation, on nusmods.com, and its own specification names mods@nusmods.com as the contact. Its description states the data is scraped daily from official APIs provided by the NUS Registrar's Office — meaning NUS does operate a course API, but not one the public can reach. No evidence of institutional endorsement or operation was found, so this is recorded as a relationship and its artifacts are deliberately not saved under NUS.
