Google Debuts New Ways to Let AI Agents Shop Like Humans

Google has enhanced its Universal Commerce Protocol with new features that enable AI agents to shop more like humans, including a "Cart" option for adding multiple items simultaneously and a Catalog capability for retrieving real-time product details like pricing and inventory. The protocol, developed with major retailers including Walmart and Target, also now supports Identity Linking, allowing shoppers to receive the same loyalty benefits across different platforms as they would when logged into a retailer's site directly.
