Check thousands of Instagram, TikTok and X handles at once — active, private, renamed or deleted — with live follower counts, bios and verification status.
A bulk social-handle verification tool for Instagram, TikTok and X that checks large lists of usernames or profile URLs in a single run. It determines existence and status (active, private, not found, error), reports whether an account is private, captures live follower/following/post counts, and extracts profile metadata such as display name, bio, verification state, profile photo and any external link. The connector returns a stable numeric platform identifier and an exact UTC timestamp for each handle, emits one record per input handle (including failures), detects username renames by comparing the current platform-reported handle to the input, and supports mixing platforms freely in the same batch.
