UCP + AP2 Reference Suite is a newly published TypeScript demo that wires together four local services: a shopping agent, merchant portal, credentials provider, and payment provider. The suite includes signed JSON-RPC interactions, JWS mandates, protocol traces, conformance checks, and scenarios for successful purchases, policy failures, refunds, disputes, subscriptions, and approval workflows.
Why This Matters for UCP
UCP + AP2 Reference Suite is a practical local harness for testing full agentic-commerce flows across UCP, AP2, shopping-agent, merchant, wallet, and PSP boundaries.

Good tool for UCP conformance testing. Runs fast and the output is easy to parse in CI. Would like a JSON output mode — currently only text.

This saved us days of work. Dropped it into our pipeline and had UCP endpoint validation running in about 20 minutes. Documentation is accurate.

The best developer tool in this category. TypeScript types are correct and complete. Error messages actually tell you what went wrong.
