Embodiments described herein simplify ordering of products from online shops. This may involve an agent server receiving captured contents of a product webpage from a client device and autonomously deriving product information therefrom. Alternatively, the agent service can receive a web address corresponding to a product webpage, and the agent server can visit the product webpage and capture its contents. The agent server then uses the derived product information to autonomously control ordering of the product for the user from an online shop, without requiring that the user have an account with the online shop, without requiring that the user enter personal and payment information in a check-out webpage of the online shop, without requiring that the user select a buy or shopping cart button associated with the online shop, and without requiring the online shop utilize an API to enable the agent server to interact with the online shop.
