  title: Gitee Open API v5 (core subset)
  description: >-
    A curated, representative subset of the Gitee (码云) Open API v5, the
    documented REST API of the China-based Git hosting and DevOps platform
    operated by OSChina / Shenzhen Oschina (开源中国). Every path in this document
    is grounded in Gitee's live Swagger definition at
    https://gitee.com/api/v5/swagger_doc.json (Gitee Open API version 5.4.92 as
    observed on 2026-07-12); the authoritative, complete machine-readable spec
    (175 paths / 264 operations across Repositories, Issues, Pull Requests,
    Users, Organizations, Gists, Enterprises, Webhooks, Labels, Milestones,
    Activity, Git Data, Search, and more) lives there. This subset captures the
    core representative operations per resource group. Requests authenticate
    with a personal access token supplied either as an `access_token` query
    parameter or an `Authorization: Bearer <token>` header, or via OAuth2.
    English endpoint summaries below are translated from the Chinese summaries
    in the source spec.
