description: 'causaLens is a London-headquartered enterprise AI company and a pioneer
  of Causal AI — machine intelligence that models cause-and-effect relationships rather
  than correlation alone. Its commercial platform, decisionOS, is a decision-making
  operating system that combines causal discovery, causal graph modelling, and multi-agent
  "Digital Knowledge Workers" that automate repetitive data-science and analyst workflows
  for enterprises. The platform is delivered as a hosted product plus a Python-first
  interface, and is distributed through the Microsoft Azure Marketplace and the UK
  G-Cloud Digital Marketplace. causaLens also maintains Dara, an Apache-2.0 open-source
  Python application framework for building interactive, decision-support web apps,
  published on GitHub with packages on PyPI and npm and full public documentation.'

- name: Dara Application Framework HTTP API
  description: 'The HTTP surface exposed by a Dara application. Dara is causaLens''
    Apache-2.0 open-source Python framework built on FastAPI; each app serves a documented
    set of built-in routes (session verification, token refresh, file upload) and lets
    developers register custom REST endpoints with the dara.core.http get/post/put/patch/delete
    decorators. Dara applications are self-hosted, so there is no single vendor-operated
    base URL — the base URL is whatever host the operator deploys the app to.'

  x-base-url-note: 'Self-hosted framework — no vendor-operated production host exists.
    No baseURL is recorded rather than fabricate one; api.causalens.com does not resolve.'
