What builders are doing with UCP

Illustrative examples of how teams are implementing UCP today.

Illustrative example

Connected a Shopify UCP endpoint to an AI reorder agent. About a day to get working. The /.well-known/ucp discovery handles the hard part.

"Expected more friction. The endpoint just worked. Biggest issue was our own inventory sync, not UCP."

Illustrative example

Built a conversational shopping advisor that browses a UCP catalog and handles checkout. Product matching still being refined.

"Agent-assisted purchases convert better than browse-to-buy. Not a silver bullet though -- the agent gets confused by bundles."

Illustrative example

Connected one UCP endpoint to multiple AI shopping platforms. One implementation, multiple channels.

"Build it once, that was the pitch. Mostly true. Each platform has quirks but the base protocol is solid."
