Direct Universal Commerce Protocol
Universal Commerce Protocol (UCP) is the open standard that powers agentic commerce, co-developed by Google and Shopify. Building directly against UCP gives you complete control over how your products appear in AI conversations, but requires implementing the full protocol specification including capability negotiation, transaction routing, and order management.
We tested UCP integration on a custom React storefront and achieved 4-platform AI coverage in 6 weeks. The upside is zero intermediary fees and complete customization; the downside is that most merchants will get to market faster through Shopify's managed service.
