Agent-to-agent commerce works by using the A2A protocol for transport and UCP specification for secure data exchange. Agents utilize structured DataPart objects to negotiate checkout data, payment credentials, and risk signals autonomously.

Implement autonomous checkout by initiating a UCP checkout session over the A2A binding. Provide product details and payment information to let agents directly negotiate and complete transactions without human intervention using structured message parts.

The UCP A2A binding is used to facilitate secure data exchange for autonomous commerce. It enables AI agents to exchange structured checkout, payment, and risk data using DataPart objects and Agent Cards during multi-agent transactions.

Yes, you must strictly adhere to the A2A protocol for transport and the UCP specification for checkout data. Compliance is required to securely exchange payment credentials, risk signals, and structured message parts between agents.

Yes, UCP checkout handles payment authorization between agents by exchanging payment credentials and risk signals. An AI purchasing agent can directly complete a transaction with a merchant agent, handling everything from product selection to final payment.

UCP autonomous transactions require strict adherence to both A2A transport and UCP data specifications. Transactions are limited to environments where agents can properly process structured DataPart objects, Agent Cards, and risk signals.
