    note: The page exists and is titled "Upcoming Changes" but its entire body is the single word "TBD" - a placeholder,
      not a policy.
  note: 'Gemini publishes NO deprecation policy, no notice period, and no RFC 8594 Sunset/Deprecation headers. Neither
    OpenAPI marks a single operation deprecated: true. Removals are announced only retroactively in the changelog
    - /v1/feepromos was "removed from the REST API specification and TypeScript SDK" on 2026-09-10 with no prior notice
    window stated. The upcoming-changes page is the right surface for this and is empty.'
deprecated_operations: []
deprecated_operations_note: 'Zero operations carry deprecated: true across the 105 published operations.'

  published: false
  note: No public API SLA was found. The API Agreement (https://www.gemini.com/legal/api-agreement) governs use but
    states no availability commitment.
archived_surfaces:
  note: Archived WebSocket v1/v2 APIs remain documented for reference but are deliberately excluded from the current
    AsyncAPI contract (stated on https://developer.gemini.com/api-specifications).
