UCP Checkout REST Binding
Implements Universal Commerce Protocol (UCP) checkout sessions via RESTful API bindings with support for idempotency, state transitions, and error resolution.
The ucp-checkout-rest skill enables Claude to manage or implement UCP-compliant checkout workflows over REST, facilitating seamless interaction between commerce platforms and agents. It provides a structured framework for handling the entire checkout lifecycle—from session creation and negotiation to payment completion and cancellation—while strictly adhering to UCP specifications for headers, data types, and status state machines. This skill is essential for developers building agentic commerce solutions or integrating merchant backends with the UCP ecosystem, ensuring robust handling of monetary values in minor units and secure, idempotent transactions.
