summary: >-
  American Eagle Outfitters publishes no API versioning policy, no deprecation policy, no
  SLA and no status page — there is no developer programme for any of those to attach to.
  The only lifecycle signal in the estate is version negotiation on the Shopify-provided
  UCP/MCP surface, which is real and dated.

    An agent reads supported_versions from /.well-known/ucp.json, or receives
    protocolVersion 2024-11-05 from the MCP initialize handshake. Three concurrent UCP
    versions are live, which is a real backwards-compatibility posture even though no
    written policy accompanies it.
mcp_protocol_version: '2024-11-05'
deprecation_policy:
  documented: false
  sunset_header: unknown
  detail: >-
    No deprecation policy, no RFC 8594 Sunset/Deprecation header documentation, and no
    stated end-of-life date for the two older UCP versions. Their continued presence in
    supported_versions is the only signal, and it carries no commitment.

    status: NXDOMAIN
  - url: https://www.ae.com/.well-known/api-catalog
    status: 404
  detail: No AEO-operated status page found. The underlying storefront runs on Shopify, whose status page is a vendor surface and is not claimed here on AEO's behalf.

changelog:
  published: false
  detail: No dated API or developer changelog exists. www.aeo-inc.com/news-media/ is a corporate newsroom, not a release log, and is pointed at as Blog rather than ChangeLog.
