description: Contentstack versions its APIs in the URL path (v3 for content management and delivery, v1/v2 for the
  newer product APIs) and publishes a dated changelog, but no deprecation policy, no sunset schedule and no RFC
  8594 Deprecation/Sunset headers. Breaking changes are announced in the changelog only.
versioning:
  scheme: url-path
  current: v3
  evidence: '"The API version (in our case, ''v3'') can be found in the URL, e.g. api.contentstack.io/v3/endpoint."
    — https://www.contentstack.com/docs/developers/apis/content-management-api'
  note: 'Not uniform across the estate: Content Management and Content Delivery are /v3, Launch Analytics is /v2,
    Automation Hub and Personalize are /v1, and the SCIM, BrandKit and Personalize Edge surfaces are unversioned
    in the path.'
deprecation_policy:
  published: false
  evidence: No deprecation or sunset policy page exists; the strings "deprecat" and "sunset" appear nowhere in the
    Content Management API reference except a note about the retired Postman Chrome extension.
  headers:
    deprecation: false
    sunset: false
    rfc8594: false
  openapi_deprecated_operations: 0

sla:
  published: true
  value: 99.5% uptime SLA, Enterprise plan only
  evidence: https://www.contentstack.com/pricing — Enterprise tier lists a 99.5% uptime SLA; Free and Growth tiers
    do not.
breaking_change_observed:
  date: '2026-09-11'
  change: The limit query parameter now accepts positive integers only; limit=0 no longer returns all records.
  source: https://www.contentstack.com/docs/changelog
  note: Announced in the changelog with no deprecation window and no Sunset header — a silent behaviour change for
    any client that passed limit=0.
