I have a project in which we have to enter a Facebook URL, after submitting the URL we have to determine if this URL is for a personal profile or a public page.

the URL of personal profile and public pages have the same structure for example:

personal profile: https://www.facebook.com/zuck

public page: https://www.facebook.com/cnn

so I need a programmatically way using HTTP request or whatever possible to figure it out what is this link for.

I tried doing that with Facebook graph API but I couldn't find out how.
