# University of Bonn GitLab REST API v4

**Canonical:** https://apis.io/apis/university-of-bonn/gitlab-api/  
**Provider:** University of Bonn — https://apis.io/providers/university-of-bonn/  
**Base URL:** https://gitlab.uni-bonn.de/api/v4/projects  
**Documentation:** https://gitlab.uni-bonn.de/

University of Bonn GitLab REST API v4 is one of 12 APIs that [University of Bonn](https://apis.io/providers/university-of-bonn/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include GitLab, Source Code, REST, Research Software, and Self-Hosted. The published artifact set on APIs.io includes API documentation.

The University of Bonn self-hosts GitLab at gitlab.uni-bonn.de and its REST API v4 answers anonymous callers over the public project set. Verified live 2026-09-01: GET /api/v4/projects?per_page=1&simple=true returned 200 application/json with x-total 195 across 195 pages and ratelimit-limit 60; a 100-item page returned 97,168 bytes of project metadata. Privileged endpoints are properly closed — /api/v4/metadata and /api/v4/version both return 401 Unauthorized without a token. The GitLab API contract belongs to GitLab; the instance, the projects and the data are Bonn's, so the relationship is recorded and no GitLab specification is saved here.
