Google recently unveiled Universal Commerce Protocol (UCP), a new open standard for agentic commerce that the search giant claims works across the entire shopping journey — from discovery and buying to post-purchase support. UCP establishes a common language for agents and systems to operate together across consumer surfaces, businesses, and payment providers to enable commerce. So instead of requiring unique connections for every individual agent, UCP enables all agents to interact easily. The protocol has backing from some of the biggest American retailers and payment players including Walmart, Target, Shopify and Etsy.
