description: >-
  Buttondown publishes exactly one first-party package: the @buttondown/cli npm package, which
  is a content-sync CLI rather than a server-side API client library. There is no first-party
  SDK on npm, PyPI, RubyGems, crates.io, Packagist, Maven Central, NuGet or pkg.go.dev — the
  documented integration path is raw HTTP against the REST API. Every other Buttondown-named
  package found on a registry is third-party.
