profiles Guides

Every Facebook pipeline starts with the same two questions: which entity is this URL, and what does the world see of it. Facebook URLs are notoriously polymorphic — profiles, pages, groups, posts, profile.php?id= forms, people/ aliases — and guessing wrong wastes every downstream call. Two endpoints settle it.

Before trusting an Instagram account — a seller in your marketplace, an influencer pitch, a counterparty in a deal — you check the About this account screen: which country the account declares, when it was created, how many usernames it burned through. That screen has an API counterpart, and it is one call: GET /user/about/{user_id}.
