summary: >-
  ZBiotics publishes no API versioning policy, no deprecation policy, no SLA and no status page of
  its own. What it does publish is a dated protocol version, and it keeps two superseded versions
  addressable - which is a de facto version policy inherited from the Universal Commerce Protocol
  rather than authored by the company.
versioning:
  scheme: dated-protocol-version
  current: '2026-08-25'
  location: >-
    Declared in /.well-known/ucp.json as ucp.version, and echoed on every MCP response as the
    header x-shopify-ucp-mcp-api-version.

  policy_published: false
  note: >-
    Three dated versions are concurrently addressable, but nothing states how long a version is
    kept, how much notice precedes a removal, or who decides. The version ladder is real; the
    policy governing it is not published.
deprecation:
  policy_published: false
  sunset_header: false
  deprecation_header: false
  rfc8594: false
  deprecated_operations: []
  detail: >-
    No Deprecation or Sunset response header was observed on any probed response, and no
    deprecation notice appears in any tool description or in llms.txt. No Deprecation pointer is
    emitted.
status_page:
  published: false
  url: null
  detail: >-
    ZBiotics operates no status page. The underlying platform publishes status.shopify.com, but
    that is Shopify's page about Shopify, not a ZBiotics commitment about this endpoint, and
    wiring it would credit ZBiotics with an operational surface it does not run. No StatusPage
    pointer is emitted.
sla:
  published: false
  detail: No uptime, latency or support-response commitment is published for the agent surface.
changelog:
  published: false
  detail: >-
    No dated API changelog exists. The company blog at /blogs/journal is product and science
    writing, not release notes - the most recent entry indexed in the sitemap is dated
    2026-09-03 and concerns the product, not the API. No ChangeLog pointer is emitted.
maturity:
  server_version: 0.1.0
  detail: >-
    initialize reports serverInfo name universal-commerce version 0.1.0. That is the platform
    implementation's own version string and should not be read as a ZBiotics release number.
