LIVE @ Google I/O: Universal Cart, Agentic Payments, and the Protocols Powering the Agent-Mediated Economy

Google is advancing "agentic commerce" through three foundational pillars: the Universal Commerce Protocol (UCP), Agentic Payments (AP2), and the Universal Cart. UCP expands into new verticals like travel and local food delivery, while AP2 enables secure, agent-driven purchases via Gemini Spark. The Universal Cart serves as an agentic hub across Google services, managing price tracking, stock alerts, and product compatibility—illustrated by guest Suresh Ganapathy’s example of avoiding incompatible Ethernet cables for a home network. These tools aim to reduce shopping friction by allowing consumers to delegate tedious tasks to AI agents while maintaining merchant control and data privacy through tamper-proof contracts. By integrating these technologies, Google seeks to enhance consumer value and provide merchants with better visibility into customer intent, ultimately streamlining the path from inspiration to purchase.
