  Lifecycle posture across the two Morgan Stanley developer surfaces. The public
  E*TRADE V1 REST API is versioned in the URI path; the invitation-only Morgan
  Stanley institutional platform follows the Microsoft API Guidelines but its
  deprecation/SLA specifics are gated behind onboarding.
versioning:
  scheme: uri-path
  current: v1
  detail: E*TRADE resources are served under /v1 on api.etrade.com and apisb.etrade.com.
deprecation:
  policy_url: null
  sunset_header: false
  detail: >-
    No public RFC 8594 Sunset/Deprecation header policy documented on the E*TRADE
    surface. Institutional deprecation is handled per client agreement.
sla:
  url: null
  uptime_target: null
  detail: No public SLA for the developer APIs; institutional SLAs are contractual.
status_page: null
status_page_note: >-
  No dedicated developer status page was found for developer.etrade.com or
  developer.morganstanley.com. E*TRADE publishes general system status through
  us.etrade.com, not an API-specific status feed.
maintenance: >-
  E*TRADE documents scheduled system-maintenance windows via error code 670
  (HTTP 500, "Service unavailable / system maintenance").
