j-google-trends-api is a Java based implementation of Unofficial Google Trends API.
Google does not provide any API for its Trends services, this an unofficial Java implementation. Features:
- Easily authenticates to Google's services
- Parses CSV file as downloaded from Trends
- Simply queries Trends by only configuring the request parameters
- Supports Proxy configuration
A ready to use binary client for Google Trends is available here! https://github.com/elibus/j-google-trends-client/tree/master/releases/org/freaknet/gtrends/client/j-google-trends-client
- Jar library: https://github.com/elibus/j-google-trends-api/tree/master/releases/org/freaknet/gtrends/j-google-trends-api

String content = client.execute(request);
/* The default request downloads a CSV available in content */

/* Get a specific section of the CSV */
String section = csvParser.getSectionAsString("Top searches for", true);
System.out.println(section);
}
}
Google has imposed new policies to restrict traffic from bots, these can be circumvented by using a set of anonimous proxies like https://www.hidemyass.com/ . A new proxy has to be setup after 4 requests max.
