  Searched npm (registry.npmjs.org search + package metadata), PyPI, the
  AstronomyAPI GitHub organization (3 public repos), the widget CDN origin and
  the documentation set (docs.astronomyapi.com/llms.txt, /widgets.md,
  /readme.md). No first-party package is published to any language registry.

  note: >-
    Astronomy API distributes no first-party client library through a package
    registry. Its only shipped client is a browser widget bundle served from its
    own CDN at an UNPINNED URL, so a consumer cannot tell which build they are
    loading and neither can we. Everything else the provider publishes is
    example code, not a package. The one npm package that wraps the API is
    third-party.

      First-party (AstronomyAPI GitHub org, MIT). Distributed ONLY as an
      unpinned script tag — `https://widgets.astronomyapi.com/cdn/astronomy-api-widgets.js`
      carries no version segment and no registry entry exists (registry.npmjs.org
      returns 404 for both `astronomyapi-widgets` and `astronomy-api-widgets`;
      data.jsdelivr.com has no such package), so there is no metadata endpoint to
      read a version or a release date from. The repository's package.json
      declares `"version": "1.0.0"`, but that is the source tree, not the
      artifact served. version: null is therefore a measured fact, not a gap:
      the distribution floats to whatever is currently on the CDN.
      Bundle fetched 2026-09-04: HTTP 200, application/javascript, 2,185 bytes,
      defining `window.AstronomyAPI` with `moonPhase()` and `starChart()`.

      First-party example repository, not a distributable package — no registry
      entry, no release tags. Listed here because the provider's own docs point
      developers at it for code samples and as the support/issue channel
      ("Please create a ticket on Github"). Last pushed 2026-09-04.

      (misuse-upshot.7y@icloud.com), no repository, no homepage, description "An
      interface to astronomyapi.com". Not published by, endorsed by, or linked
      from Astronomy API. Recorded so the absence of an official SDK is not
      mistaken for the presence of one.
