  • Universal Commerce Protocol (UCP) Launches as Open‑Source Standard

Google has released the Universal Commerce Protocol (UCP), an open‑source framework designed to streamline agent‑driven commerce. UCP establishes a common language and set of functional primitives that enable seamless interactions between consumer surfaces, merchants, and payment providers. It supports real‑time inventory checks, dynamic pricing, and instant transactions, and is compatible with the Agent Payments Protocol (AP2). Developed with major retailers and payment partners-including Shopify, Walmart, Stripe, and Visa-UCP aims to eliminate the N × N integration bottleneck by offering a single, secure abstraction layer for discovery, checkout, and order management. The protocol also separates payment instruments from processors, allowing businesses to integrate via APIs, Agent2Agent, or the Model Context Protocol.
