I have a Facebook application that users can add to their Facebook business Page(s) as a Page Tab app. It doesn't require any extended permissions for the user. I'm wondering if it's possible to use my app access_token and make calls against the Facebook Graph API to retrieve information about age-restricted Pages?
No, if a page is restricted demographically (e.g. for alcohol) you MUST use a user access token from a user who meets those restrictions, or a Page access token for the page itself.
An app access token will not work for such an API call
If the owner of that access token can view the data on facebook you can get any data using that access token not mater if its block for the others .
