Google lays the groundwork for agent-led checkout
The launch of the Universal Commerce Protocol signals how transactions may move inside AI conversations
Google has unveiled the Universal Commerce Protocol (UCP), a new framework designed to let AI agents handle discovery, checkout, and post-purchase support directly within conversational interfaces.
Announced at the National Retail Federation conference, UCP aims to remove friction between interest and transaction by eliminating the need for multiple handoffs across systems.
While initially focused on retail, the architecture is explicitly built to support more complex transactions, including travel bookings.
The launch signals Google’s intent to shape how purchases are executed inside AI-powered experiences.
Key takeaways
- Universal Commerce Protocol (UCP): A standardized transactional layer that allows AI agents to move users from discovery to purchase without switching platforms or rebuilding integrations.
- In-conversation checkout: Purchases can be completed inside Google’s AI interfaces, using stored payment and shipping details from Google Wallet.
- Merchant control preserved: Businesses remain the merchant of record and retain ownership of customer data, fulfillment, and post-purchase relationships.
- Designed for complex transactions: Although launched with retail partners, UCP is architected to scale into categories like travel, where bookings involve multiple components and constraints.
- Broad payments industry backing: Major players such as Visa, Mastercard, Stripe, Adyen, American Express, and PayPal are supporting the protocol, accelerating adoption.
- Interoperability with agent standards: UCP integrates with Google’s Agent Payments Protocol (AP2) and is compatible with emerging standards like Model Context Protocol, used in travel infrastructure.
- Strategic positioning in AI commerce: UCP strengthens Google’s role in the competitive race to control where and how transactions happen within AI-driven conversations.
