Universal Commerce Protocol (UCP)

A protocol for agentic commerce in which an agent must not only find a product but also check availability, assemble a cart, and complete a transaction in a coherent, interoperable way. It standardizes interactions between the agent, the merchant, and the payment system so that delegating a purchase is safe. Developed by Google.
