A product catalog stores product records corresponding to data associated with different products. As a webpage is accessed by a user device, data is extracted from the merchant product webpage. The extracted data is used to identify one or more product records in the product catalog that are potential matches to the webpage. When multiple product records are identified, a remote server is used to access and interact with the webpage separate from the user device. Additional data is extracted from the webpage based on interactions by the remote server with the webpage. The additional data is used to determine a single product record for the webpage. The webpage is modified based on the single product record. ## Claims ### Claim 1 A system, comprising: a non-transitory memory; and one or more hardware processors coupled with the non-transitory memory and configured to read instructions from the non-transitory memory to cause the system to perform operations comprising: detecting a merchant product webpage being accessed by a browser application of a user device, wherein the merchant product webpage comprises a first product of a merchant;
