The statistics package contains the Statistics class that reflects the functionality documented at at https://blockchain.info/api/charts_api. It makes various network statistics available, such as the total number of blocks in existence, next difficulty retarget block, total BTC mined in the past 24 hours etc.
Example usage:
package test;
import info.blockchain.api.statistics.*;
public class App
{
public static void main(String[] args) throws Exception
{
Statistics stats = new Statistics();
StatisticsResponse stats = stats.get();
System.out.println(String.format("The current difficulty is %s. "
+ "The next retarget will happen in %s hours.",
stats.getDifficulty(),
(stats.getNextRetarget() - stats.getTotalBlocks()) * stats.getMinutesBetweenBlocks() / 60));
Chart txPerSec = stats.getChart("transactions-per-second", "5weeks", "8hours");
Map<String, Integer> pools = stats.getPools("5weeks");
}
}
