Scalar Registry Management API

openapi: 3.1.0
info:
  title: Scalar Registry (Public Read Surface) - Modeled Registry Management API
  description: MODELED / endpointsModeled. Scalar is an open-source API platform whose hosted Registry stores and versions OpenAPI documents. Published documents are served over a public HTTPS read CDN at registry.scalar.com in the form /@{namespace}/apis/{slug}, optionally with a ?format=json or ?format=yaml query to control the returned representation, and an optional version segment. This document models that public read surface plus the registry lifecycle operations that are performed through the authenticated Scalar CLI (scalar registry publish / list / update / delete). Scalar does NOT publish a fully documented public REST management API; the mutating operations below are modeled from the CLI behavior for cataloging purposes and their exact HTTP shapes are not officially specified. The one confirmed, publicly reachable endpoint is the GET read of a published document (e.g. https://registry.scalar.com/@scalar/apis/galaxy?format=json).
