# Yale Courses Web Service v3

**Canonical:** https://apis.io/apis/yale/courses/  
**Provider:** Yale University — https://apis.io/providers/yale/  
**Base URL:** https://gw.its.yale.edu/soa-gateway/courses/webservice/v3/index  
**Documentation:** https://developers.yale.edu/courseswebservicev3

Yale Courses Web Service v3 is one of 13 APIs that [Yale University](https://apis.io/providers/yale/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Course Catalog, Courses, Registrar, and Gated. The published artifact set on APIs.io includes API documentation.

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.
