UCP Core Summary: A deep dive into the Universal Commerce Protocol framework designed for Agentic Shopping.
The Next Evolution of Payment Security
When an AI agent makes a purchase on your behalf, how do we ensure it isn’t tricked? The answer is the Agent Payments Protocol (AP2), a core sub-layer of UCP—operators must also plan AP2 token revocation for agent payment credentials.
Cryptographic Proofs
AP2 relies on biometric cryptographic proofs from the user’s device. The agent never actually holds raw credit card numbers. Instead, it holds a one-time, cryptographically signed intent token.
Zero-Knowledge Commerce
The merchant validates the AP2 token with the payment gateway, ensuring the transaction is mathematically guaranteed without exposing the user’s underlying financial data to the AI.
