title: Best API to see if an account exist in Instagram?
body: <p>I have a list of usernames, with this list, I want to see if an Instagram account with such username exists programmatically. </p>
  
  <p>What is the best tool (or an API) to use to input a list of usernames and parse the information of whether an account exists or not?</p>
  
  <p>Thanks</p>
