• sending, from the mobile device, a search request to a remote e-commerce platform for a responsive set of candidate items, wherein:
• the search request requests candidate items that are determined to have attributes similar to the plurality of attributes of the object,
• the search request causes a first subset of responsive candidate items to be selected from a first set of items obtained from a first vendor's online product-listings via a first application-program interface (API) connection, and
• the search request causes a second subset of responsive candidate items to be selected from a second set of items obtained from a second vendor's online product-listings via a second API connection, the second vendor's online product-listing being different from the first vendor's online product listing, and the first API connection being different from the second API connection;
• receiving, with the mobile device, the first subset of responsive candidate items and the second subset of responsive candidate items;
• and
• presenting, with the mobile device, descriptions of the first subset of responsive candidate items and descriptions of the second subset of responsive candidate items in a user interface.
