Java

The code sample below calls the API's search.list method with type, q, location and locationRadius parameters to retrieve search results matching the provided keyword within the radius centered at a particular location. Using the video ids from the search result, the sample calls the API's videos.list method to retrieve location details of each video.

This example uses the Java client library.
