How to calculate retweet of any URL, without login from Twitter API

Question

I am new to twitter API. Is there any way that i can get number of retweet of any URL. I want to calculate it without any login into twitter.

Answer 1

What do you want to calculate? How effective your marketing strategy is?

This is not possible via twitter.

Of course you can do: use the search API via link:yourlink or you could use bit.ly and their statistics to see who tweeted about destinct urls. Another solution could be our http://jetwick.com where we will release api access in some weeks.
