Courses@Brown (Leepfrog CourseLeaf tenant) is one of 7 APIs that [Brown University](https://apis.io/providers/brown/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Course Catalog, Registrar, and Student Information.

Brown's course search and registration front end. It exposes a live, public, keyless JSON API at cab.brown.edu/api/ — a POST interface with page=fose routes for search and details that returned 393 course sections with CRNs, meeting times, instructors, enrolment caps and grade-mode options for a single keyword query on 2026-08-30. This is by some distance the richest machine-readable Brown data on the public internet, and it is not Brown's engineering: the host is a CourseLeaf tenant and the fose search interface is Leepfrog's product. Recorded as a tenant relationship; no CourseLeaf contract is saved under this slug. Brown operates no course or registrar API of its own — the student-built api.students.brown.edu that once did has been 404 since before this profile was written.
