I too have been looking for this exact same solution, ive downloaded this .jar programme it seems to do something but leaves an ampty out.txt file - any ideas? Ive got internet connection and it does the same thing with the test in.txt file so its not the formatting of the in.txt file.
Bc.i changed their API you can either use the source and change it to your needs or use the curl version I wrote a bit later[1] thats working with the blocktrail.com API.

https://bitcointalk.org/index.php?topic=736607.msg9982506#msg9982506Sorry to be really dim but im not sure how I implement the script on windows? I tried putting this in a .bat file but didn't work.
Not sure how to get it to work on windows. You need curl[1] and something similar to grep. You will also need an API key for blocktrail[2].
I remember I got a PM from someone saying they got the curl version running on windows, Ill see if I still have the PM and ask whether they can post their solution here. Nope, sorry no mention of Win.
Im also unsure which file in the source code I need to amend or how to build/compile it when I have.
I made it with eclipse 4.4[3] if you send me changes to the source I can upload a compiled version for you.
I'm guessing its the main.java in the src folder? Do I literally have to change the blockchain.info address to an another address?
Yes, the following line (#81) would have to be replaced by a similar line for another API as long as this other API returns just a number and nothing else. As you can see the curl version needs to filter the returned data.
URL bc_api = new URL("http://blockchain.info/q/addressbalance/"+check);
