This question is an exact duplicate of:
I wanted to make unlimited call to the API to retrieve/update the threads. Is there any way to do so?
I understand "Without a key you can make 300 requests per day, with a key you can make 10,000 requests per day With an access token, the 10,000 request limit is just for the app for that user. * Without an access token, the 10,000 request limit is shared between apps on the IP Address."
Is there any exception on top of this?
Do you have Rest API which can be consumed in our application?
