UCP Checkout REST Agent
Implements standardized Universal Commerce Protocol (UCP) checkout sessions via RESTful API bindings for agentic commerce.
This skill enables Claude to manage the complete lifecycle of a UCP-compliant checkout session using REST operations. It provides the logic needed to handle headers, idempotency keys, and complex status transitions while driving checkout sessions from 'incomplete' to 'ready_for_complete'. By following strict UCP specifications, it ensures seamless negotiation between platforms and businesses, automated error recovery based on message severity, and precise handling of monetary values in minor units, making it essential for developers building interoperable e-commerce agents.
