source: https://eqbuilder.dev/llms.txt ("Official SDKs", "Permanent tool setup", "Quickstart code"), registry.npmjs.org/eqbuilder,
  pypi.org/pypi/eqbuilder/json, https://eqbuilder.dev/api/starter-kit — versions and dates read live 2026-09-19
note: 'Both registry packages are first-party: the PyPI author and npm maintainer identity ("EqBuilder") carries
  the same contact address the agent card and /api/pricing publish, both set homepage https://eqbuilder.dev, and
  llms.txt names them as the official SDKs. Six versions were cut on the day of first publication (2026-08-16) and
  one follow-up (0.1.5) on 2026-09-06 on both registries within the same day — a single release train. Neither package
  declares a source repository, and no GitHub organisation was found (llms.txt mentions "the platform repo under
  examples/" without linking it).'
