  EZR publishes NO client library on any public package registry. Searched npm, PyPI,
  RubyGems, crates.io, Packagist, NuGet, Maven Central and pkg.go.dev for ezr / ezrpro /
  driver names — nothing first-party. What it does distribute is two versioned sample projects
  as raw zips from its own CDN (apidoc.ezrpro.com), linked from the developer guide, plus a
  packaged Agent Skill. Those are recorded below with the version read from the pinned URL,
  because there is no registry metadata endpoint to query. No SDKs pointer is emitted in
  apis.yml: a downloadable demo project is not a maintained client library, and claiming one
  would credit EZR with an SDK it does not ship.

    .NET sample calling the EZR Open Platform. No registry metadata endpoint exists, so the

    HTTP only; https on this host is answered by the same CDN but the guide links http.

  note: >-
    The distribution URL itself is UNPINNED — it floats to whatever is current at
    /skills/ezr-skills-openapi.zip — so a consumer cannot tell from the link which build they
    are getting; the version is only visible after unzipping. Captured verbatim in skills/.
