Universal Commerce Protocol (UCP)

The Universal Commerce Protocol defines capabilities for agents to shop: discovery at /.well-known/ucp, checkout, orders, and extensions such as AP2 mandates. It is moving quickly, with lodging booking and a common ask capability merged in 2026 and food checkout under review.
