        Oviond API key (prefix `oviond_`) sent as a Bearer token — the
        credential for REST/programmatic and headless integrations. Manage keys
        in Settings → API Keys. API keys do NOT authenticate the MCP endpoint
        (/mcp), which uses OAuth 2.1 + PKCE.
    BearerAuth:

      scheme: bearer
      bearerFormat: JWT
      description: >-
        Supabase-issued JWT used by the Oviond web app session. External API
        consumers should authenticate with an Oviond API key (ApiKeyAuth)
        instead.
