Hello LeBraat 
Thank you so much for your answer.
We thought you had abandoned us.
I mention the following:
1.- EndPoint: account / verify_credentials. The user when they log in for the first time, receives the information of their profile. That is, ProfileImageURL, Name, ScreenName, etc.
2.- EndPoint: followers / ids. The user gets his followers, friends, favorites, etc.
Analyzing your answer, please, you could indicate us:
What volume are we making calls to the EndPoint: account / verify_credentials ?. What are the limits ?.
What volume are we making calls to the EndPoint: followers / ids ?. What are the limits ?.
Waiting for an answer from you, receive a cordial greeting.
