Cirkul Storefront Agent API is published by [Cirkul](https://apis.io/providers/cirkul/) on the [APIs.io](https://apis.io/) network. Tagged areas include Agentic Commerce, MCP, Universal Commerce Protocol, E-Commerce, and Catalog. The published artifact set on APIs.io includes authentication docs.

The agent-facing commerce surface Cirkul serves from its own drinkcirkul.com host. It comprises an anonymous Model Context Protocol (MCP) server at /api/mcp exposing five tools with real JSON Schema inputs (search_catalog, get_cart, update_cart, search_shop_policies_and_faqs, get_product_details), a Universal Commerce Protocol merchant discovery profile at /.well-known/ucp declaring cart, checkout, fulfillment, discount, order and catalog capabilities plus Shop Pay, Google Pay and card payment handlers, and a UCP shopping MCP endpoint at /api/ucp/mcp whose tools/list is gated behind a UCP agent-profile URI. Read-only catalog JSON (products.json, collection products.json) is documented for agents that only need to browse. Checkout explicitly requires contemporaneous human buyer approval.
