Google's Universal Commerce Protocol (UCP) is the standard that lets Gemini, Google AI Mode, and Google Shopping AI transact with merchant stores in real time. Brands without a UCP manifest are invisible to Google's AI buyers.
Asva generates your UCP manifest, deploys your ACP-compatible checkout endpoints, registers your catalog, and handles Google's verification process — typically in under a week.
// /.well-known/ucp — Your UCP manifest
{
"version": "1.0",
"merchantId": "your-brand-com",
"capabilities": {
"dev.ucp.shopping.checkout": {
"versions": ["1.0"]
},
"dev.ucp.shopping.order": {
"versions": ["1.0"]
}
},,
"endpoints": {
"checkout": "https://yourbrand.com/api/ucp/checkout",
"orderStatus": "https://yourbrand.com/api/ucp/order"
}
}
Asva generates and deploys this for you.
UCP isn't just a manifest file. It unlocks your store across Google's entire AI commerce surface.
When a user asks Gemini to buy something, it queries UCP-verified merchants. Without UCP, your store doesn't exist in Gemini's commerce flow.
Google AI Mode shopping results show UCP-verified merchants prominently — with buy buttons and real-time pricing. Non-UCP merchants appear as standard blue links.
UCP integration means Google Shopping AI shows your live stock and pricing — not cached data from a feed uploaded 24 hours ago.
All Google AI-initiated purchases are tagged separately in your OMS and GA4, so you can measure the channel's actual contribution to revenue.
UCP agents call your ACP checkout endpoint, which wraps your existing checkout. Your fraud detection, promotions engine, and order management remain unchanged.
Google prioritizes merchants with higher catalog quality scores in UCP results. Brands that integrate early build this advantage before competition increases.

Your products registered as a source for Gemini shopping responses and recommendations.
Google AI Mode optimization
Product schema and catalog quality optimization for Google AI Mode's shopping surface.
Attribution setup in GA4

Ongoing compliance monitoring
As Google updates UCP requirements, Asva monitors and updates your integration to stay compliant.
