Hi Bhushan, You can find specific information about rate limiting on our dev site . The main reason for seeing a rate-limit is that you, or your IP, have made too many requests over the measured time.
One of many reasons for this happening is if you are using shared hosting. It could be that somebody else with your IP is also making requests from Twitter. One way of approaching this is to use authenticated calls. This way your application is identifiable over any other request on the same IP. Hope that helps explain what could be happening.
