Superfish is a visual search technology that lets users use images instead of keywords as search queries for products. When a user inputs an image query, the visual search software extracts visual features and searches through an index of images to find those that are most similar to the query. Superfish offers developers the chance to integrate visual search functionality on their applications or web sites through the Superfish API. The API lets developers create a customized visual search experience for their users. Clients can send an image URL or the image itself and Superfish will return a set of visually similar product offers in JSON format. Developers should contact Superfish for more details and technical documentation.
According to Mozilla, more than half a billion browser add-ons are in use on Firefox alone. But unlike an app in an App Store, browser add-ons cost nothing to use. So browser add-on developers like us have had to turn to other options to generate revenue for our hard work.
