i am building a website where you can get services for your Instagram account, i want to create a Search box that when you put your user name (e.g. "@John") it returns your profile picture and asks you if that is the correct profile (without logging in to your Instagram account), I've found a website that made that possible already, does any one know how?!
the website - https://app.get-notch.com/acquisition/instagram-username
thank you in advance!
