        183 operations. The public, documented consumer surface is the
        HTTPBasic-secured subset (timeseries, metadata, symbology, batch,
        security_master, corporate_actions, adjustment_factors) - curated
        per-product specs live in openapi/databento-*-api-openapi.yml. The
        remaining tags (auth, billing, users, teams, licensing, registration,
        dataset, docs, latency, analytics, display) are the user portal's own
        endpoints, exposed in the spec but not part of the documented public
        API reference.
    description: >-
      Official Databento platform OpenAPI covering the historical/reference
      HTTP API and the user portal surface. Authenticate public API calls with
      HTTP Basic - the db- prefixed API key as username, empty password.
