If I am attempting to retrieve tweets via JS using the following URL: http://search.twitter.com/search.json?q=TWITTER-UERNAME will this work past March 5th (2013) without the server side authentication?
No, it will not. All unauthenticated requests, whether client-side performed or otherwise, will cease functioning.
Thank You for the clarification!
@episod - Hi can we call twitter API 1.1 using javascript and ajax? If so could you please give an example of how to retrieve tweets of a particular user / suppose I would like to get the profile image. How to do that?
