  notes: >-
    Deployed-flow and document-upload endpoints authenticate with a Bearer public API key (the
    organization token), passed in the Authorization header. API keys are generated in the StackAI
    console under Settings -> API Keys and can be personal or organization scoped. Some management and
    analytics endpoints declare an OAuth2 password-grant token scheme (tokenUrl "token"). No scopes are
    defined on the OAuth2 flow.
