Regarding twitter search API request limit


On the twitter Rate Limiting page( it says

“Unauthenticated calls are permitted 150 requests per hour. Unauthenticated calls are measured against the public facing IP of the server or device making the request.”

Is that the measurement based on enduser IP address or the server IP(ip of ?
Is there a way to increase the limit may be through some paid service of Twitter ?



The limits are based on the IP address as we see it incoming to our servers – so if it’s a server-to-server call, it’d be the IPs of your servers. We do not yield heightened API calls for unauthenticated requests. The best way to scale your application’s access to data is by leveraging authorization/OAuth.


Ok, i have a doubt here, Then how the Big sites are working like HootSuite(
I think they are also depending on the Twitter API, hundreds of requests are requesting to twitter API. Then how they are working?
can you please explain. I am very interesting on this topic.
