  description: >-
    Access to the Scalar hosted platform (Registry publish/manage, Docs
    deployment, SDK generation, Agent/MCP) is authenticated with a Scalar API
    key created in the Scalar dashboard (dashboard.scalar.com) and used by the
    Scalar CLI once you run `scalar auth login`. Scalar does not publish a fully
    documented public REST management API, so the exact header name and request
    shape are not officially specified - the CLI handles authentication on your
    behalf. The public registry read CDN
    (registry.scalar.com/@{namespace}/apis/{slug}) requires no auth for public
    documents. Authentication scheme is modeled (endpointsModeled).
