What is Universal Commerce Protocol (UCP)?

The UCP and AP2 documentation details the seamless integration of the Universal Commerce Protocol (UCP) with the Agent Payments Protocol (AP2), facilitating secure and verifiable transactions executed by AI agents or platforms on behalf of users, thus enabling commerce systems to handle discovery, checkout, and payment processes independently of intermediaries. The full compatibility between UCP and AP2 creates a trust framework for agent-led transactions, which requires a secure and cryptographically verifiable exchange of intent and authorization between businesses and platforms through Verifiable Digital Credentials (VDCs); this system ensures that businesses obtain signed checkout commitments that remain unchanged throughout the transaction process, while platforms deliver proofs of payment authorization that are directly associated with the state of the cart, significantly reducing the risk of fraud and confirming that transactions are both conclusive and authentic. Moreover, this integration not only streamlines the transaction process but also significantly boosts the overall efficiency and reliability of digital commerce ecosystems, ultimately fostering greater confidence among all participants in the marketplace.
