  note: 51offer publishes no first-party client library for its API on any registry. Its GitHub organisation holds
    11 public repositories - an iOS mobile-CI harness, a technical blog, and forks of third-party Objective-C/Swift
    UI components (SVPullToRefresh, RATreeView, SDCycleScrollView, XLForm, PagingMenuController) - none of which
    is an API client. The single npm package that names 51offer is a personal front-end build plugin, recorded below
    as unofficial for completeness. No SDKs pointer is emitted.

    more than a decade stale.
