Uncap’s Jerseys Campaign
Introducing agentic commerce to the world
Uncap’s Jerseys Campaign is our way of making agentic commerce tangible for commerce and developer communities—using one image to communicate what often takes pages of explanation. Each jersey is an editorial concept, not merchandise. So unfortunately, we will not be shipping it :)
Google’s Universal Commerce Protocol initiative connects retailers, commerce platforms, payment networks, and technology partners through an open specification spanning discovery, checkout, identity, and post-purchase workflows.

OpenAI and Stripe’s Agentic Commerce Protocol links agent-native product discovery and checkout with commerce platforms, merchants, and payment partners.
