Abstract: A system retrieves and synthesizes product information from multiple purveyors and provides comparative purchasing options. An orchestration service can be implemented on a computing device based on a first request to establish a connection with individual accounts associated with a system account. A connection can be proxied with a server from the orchestration service to connections established with a plurality account specific product information sources (“ASP sources”). Accounts that are held with purveyors associated with the ASP sources and associated with the system account can be accessed, and the system can facilitate, with the server, a transmission of account specific product information (“ASP info”) from the accounts to the orchestration service.
