Handling large API calls


My application wants to handle large API calls . My application is going to get user tweets , mentioned tweets , followers and also wants to send direct message to users. I am having more than 50,000 users . I just want to know how many API calls can be handled in an hour and also I want daily limit of API calls . Is there any chance to extend API calls or can I have partnership link ?.So that I can extend my API calls.


Take a look at the [node:10066] documentation on this site for an idea of the constraints you’ll have when working with Twitter data.
