summary: >-
  American Eagle Outfitters publishes no developer authentication surface — there is no API
  key programme, no developer portal and no documented auth page on www.ae.com or
  www.aeo-inc.com. The only machine-readable auth metadata in the estate is served by
  Shopify on the AEO brand storefront www.unsubscribed.com: a full OpenID Connect discovery
  document and an RFC 9728 OAuth protected-resource document for customer accounts. The
  UCP/MCP commerce endpoint itself takes no credential on discovery.

    The UCP shopping server identifies the calling agent by a profile URI rather than a
    bearer token. Discovery is anonymous; any invocation without a profile URI returns
    JSON-RPC error -32001 with data.code invalid_profile_url.
