The URX App Search API lets you access a knowledge graph that organizes apps by their content and by the actions they allow users to take. You provide specific details about the user’s context (e.g. location, keywords, time, intended action). The API then replies with the deep links and other meta data of relevant apps that you can display to the user. The RESTful URX API provides an easy way to link interactions within an app via deep linking tactics to retrieve information or perform actions within other apps. URX is accepting applicants through an online email signup that can be accessed from their website.
