VercatusGoogle native commerce checkout eligibility
On Google, only products whose Merchant Center data sets native_commerce(checkout_eligibility) to true show the UCP-powered Buy button in AI Mode and Gemini; the attribute is optional, a group with one boolean sub-attribute, and can be sent in TSV/CSV, XML (g:native_commerce) or through the Merchant API. UCP-powered checkout is available to select merchants in early access and needs a Merchant Center account, a Google Pay & Wallet Console account, the technical UCP implementation and the merchant remaining seller of record; Google's help covers products eligible in the US, Canada and Australia, and payment currently uses card numbers (FPANs) stored in Google Wallet.
