The agent-facing commerce surface of the PRIME online store. Served from drinkprime.com, it implements the Universal Commerce Protocol (UCP) shopping service over MCP transport: a discovery document at /.well-known/ucp declaring supported UCP versions, services, capabilities and payment handlers, and a JSON-RPC MCP endpoint at /api/ucp/mcp that answers tools/list anonymously with thirteen tools covering catalog search and lookup, product retrieval, cart create/read/update/cancel, and checkout create/read/update/complete/cancel plus order retrieval. complete_checkout requires an idempotency key and buyer approval.
