The Paperless Post Party Shop storefront is the only machine-callable surface on any paperlesspost.com host. It is Shopify-hosted and implements the Universal Commerce Protocol (UCP) for agent-driven commerce: a UCP merchant profile at /.well-known/ucp, an MCP endpoint at /api/ucp/mcp carrying the search_catalog / create_cart / create_checkout / update_checkout / complete_checkout tool set, OAuth 2.0 + OpenID Connect customer-account authorization, published agent instructions at /llms.txt and /agents.md, and anonymous read-only product and collection JSON endpoints. Checkout completion requires contemporaneous buyer approval.
