  No first-party client SDK is published to a language package registry (npm, PyPI,
  crates.io, Maven, NuGet, RubyGems, Packagist, Go modules all returned no
  first-party Harmonic client library). Integration is via the public protobuf
  definitions (Jito-searcher-proto compatible) and the open-source validator clients,
  distributed as source on GitHub.
