Yale University

Yale Courses Web Service v3

Returns course-offering information for a given termCode and subjectCode — titles, descriptions, instructors, meeting times, prerequisites and distributional designations — in JSON or XML. Live and gated: an anonymous request to the documented endpoint returned HTTP 400 "Invalid API Key" on 2026-08-19. A key requires registering an application in the Yale Developer Portal, which requires a Yale NetID. The previous profile of this repository described the service as returning "public information"; the payload may be public information but the surface is not public access, and that is corrected here.
