  Registry sweep of PyPI, npm, Maven Central, NuGet, pkg.go.dev, RubyGems, Packagist and
  crates.io. Chai Research has published first-party Python client libraries only. All of
  them are currently DEPRECATED or WITHDRAWN: `chai-guanaco` explicitly redirects users to
  `chaiverse`, and `chaiverse` itself no longer resolves on PyPI (both the JSON API and the
  /simple/ index return 404). No first-party JavaScript, Go, Java, .NET, Ruby, PHP or Rust
  client library was found. Because no maintained client library is currently installable,
  this artifact deliberately carries a `Packages` pointer only and NOT an `SDKs` pointer.

  description: The Chaiverse developer-platform client that `chai-guanaco` points users to.
    Referenced across Chai's own material and third-party guides, but no longer published —
    both the PyPI JSON API and the PEP 503 simple index return 404. The GitHub repository
    it was published from (chai-research/chaiverse) also returns 404.

    note: >-
      https://pypi.org/project/chaiverse/ returns HTTP 200, but the body is PyPI's
      "Client Challenge" bot-interstitial, not a project page. A 200 is not evidence —
      the JSON API and the simple index are the authoritative checks and both 404.
