  PyPI registry (pypi.org/pypi/thetadata/json), npm registry search, and the
  ThetaData docs (docs.thetadata.us/Python-Library/Getting-Started.html,
  Articles/Getting-Started/Getting-Started.html). Maven Central, NuGet,
  RubyGems, Packagist, crates.io and pkg.go.dev show no first-party ThetaData
  client libraries.
description: >-
  First-party and community client packages for ThetaData. The official Python
  library (thetadata on PyPI, v1.0.9 at capture) authenticates over HTTPS and
  requests data over gRPC directly — no Theta Terminal required. The Theta
  Terminal itself is distributed as an auto-updating Java JAR download rather
  than through a package registry. The thetadatadx-* npm packages are
  community-published (publisher userfrm), not first-party.
