UCP Embedded Checkout Protocol
Facilitates secure, iframe-based human escalation for agentic commerce checkouts using the Universal Checkout Protocol.
This skill implements the UCP Embedded Checkout Protocol (EP), enabling AI agents to transition seamlessly from automated API-based checkouts to merchant-hosted UIs when human intervention is required. It manages the complex JSON-RPC 2.0 communication flow over postMessage between the host platform and the merchant's iframe, handling critical tasks such as payment credential acquisition, cart synchronization, and fulfillment address updates while maintaining strict security standards like CSP and sandboxed environments.
