3GPP

3GPP Forge API

The 3GPP Forge (forge.3gpp.org) is a self-managed GitLab instance where 3GPP publishes the machine-readable OpenAPI for the 5G Service Based Architecture, the NEF/SCEF northbound exposure APIs, CAPIF and the SA5 management services. Its GitLab v4 REST API answers anonymously for public read operations, which makes it the one genuinely callable API surface 3GPP operates: projects, branches, release tags and raw specification files can all be fetched programmatically. Verified on 2026-07-25 (GET /projects and /projects/{id}/repository/tags return JSON without credentials; authenticated-only endpoints such as /version return 401). The API contract is GitLab's, not a 3GPP specification, so no OpenAPI is mirrored here.
