Curie (Curie Vision, Inc.) is the commerce layer for AI — it connects AI assistants like ChatGPT, Claude, and Gemini to real product catalogs from 5.6M+ Shopify stores via the Model Context Protocol (MCP). Results carry live prices, real inventory, affiliate purchase links, and interactive 3D digital twins (GLB/USDZ) that shoppers can rotate and view in AR. Curie publishes a public REST catalog API, a hosted MCP server exposing 30 commerce tools, and cross-protocol discovery profiles (MCP, UCP, A2A, OpenAI Apps SDK). Most discovery and tool calls run on a free public tier with no auth; a Pro Bearer is required only for premium tools such as checkout. Backed by 500 Global.
