description: 'Arlettie is a Paris-founded (1994) operator of invitation-only luxury and contemporary
  fashion private sales — "ventes privées" / sample sales — running showroom events in Paris, London,
  Milan and New York for more than 220 brand partners, alongside its online outlet store "Les échappées".
  Its machine-readable surface is not a developer program: it is an agent-commerce surface on the
  Les échappées storefront, which runs on Shopify and therefore serves a live unauthenticated
  UCP/MCP endpoint, agent instructions at /agents.md and /llms.txt, RFC 8414 + RFC 9728 OAuth
  discovery documents, and an introspectable Storefront GraphQL API — all on hosts Arlettie controls.'

  detail: >-
    Arlettie runs no developer program, but its Les échappées storefront serves a live unauthenticated
    UCP/MCP endpoint, agents.md, llms.txt and RFC 8414 + RFC 9728 OAuth discovery documents on a host
    Arlettie controls, plus an introspectable Storefront GraphQL API. The agent surface is real and was
    captured; there is no OpenAPI anywhere and no A2A agent card on any host.
