ap2-a2a-extension

AP2 payment mandates are transmitted between agents as A2A DataParts. This skill implements the Agent Payments Protocol as a direct extension of A2A, structuring Intent, Cart, and Payment mandates within standard A2A message structures for inter-agent payment communication.

AP2 protocol integration standardizes how autonomous agents communicate payment intents and execute transactions. It extends the Agent-to-Agent protocol to handle payment-specific task flows, enabling shopping agents to securely initiate and process payments with merchant agents.

You declare AP2 payment capabilities directly within Agent Cards to enable discoverability. This allows agents in a multi-agent system to recognize that a peer agent supports AP2 standardized payment flows and can process transmitted payment mandates.

Yes, cryptographic signing is supported within A2A message structures for AP2 payments. This ensures that payment mandates transmitted as DataParts between agents remain secure, authenticated, and standardized across multi-agent payment flows.

You need AP2 as an A2A extension when your multi-agent system requires standardized payment communication, such as a shopping agent initiating a transaction with a merchant agent. It provides the necessary payment-specific task flows and mandate structures lacking in standard A2A communication.

Yes, A2A DataParts are used to transmit all AP2 mandate types including Intent, Cart, and Payment. This allows agents to exchange structured payment data and execute standardized payment-specific task flows within the A2A protocol framework.
