Google announced the Universal Commerce Protocol (UCP), an open-source standard developed with Shopify, Etsy, Wayfair, Target, and Walmart to enable agentic commerce. UCP provides a single abstraction layer connecting consumer surfaces (like AI search and Gemini) to business backends, supporting real-time inventory, dynamic pricing, and instant transactions within conversational contexts. The protocol features a unified integration point, standardized language for discovery and capabilities, extensible architecture for emerging agentic experiences, and security-first design with tokenized payments and verifiable credentials.
