AP2 Verifiable Digital Credentials (VDC) Framework
Implements the AP2 VDC framework to create, sign, and verify tamper-evident digital credentials for secure agentic commerce transactions.
The AP2 VDC Framework skill provides the essential trust foundation for agentic payments by implementing the Verifiable Digital Credentials specification. It enables developers to manage the entire lifecycle of Cart, Intent, and Payment Mandates using the SD-JWT format with Key Binding (+kb). By facilitating cryptographic signing, JCS canonicalization, and multi-party verification, this skill ensures that AI agents can carry out authorized transactions while maintaining non-repudiation and tamper evidence. It is particularly useful for developers building autonomous shopping agents or payment gateways that require rigorous, W3C-aligned authorization models for human-to-agent and agent-to-merchant interactions.
