UCP (Universal Commerce Protocol) is an open standard to make commerce interoperable between platforms, AI agents, and merchants.
This repo curates:
- the core UCP spec
- SDKs and reference implementations
- client/server examples
- related protocols and tooling
If you’re building agentic shopping flows, commerce automation, or system-to-system checkout without one-off integrations, this is meant to save you time and reduce glue code.
Built a free validator for this at ucptools.dev - checks /.well-known/ucp
compliance against the spec and gives A-F grading with specific fix
recommendations.
Interesting finding: tested major retailers and even google.com returns
404 on their UCP endpoint. Early days.
Also made an Apify Actor for bulk validation if anyone needs to check
multiple domains programmatically.

Early ecosystem, contributions welcome.
