Data API / X / User

Batch Get User Info By UserIds

Resolve many X users at once from their numeric user IDs, passed as a comma-separated userIds string. Use this when a previous call (timeline, retweeters, followers) gave you IDs and you need to turn them into full profiles in one request instead of looping. Returns an array of user objects under users. Note this endpoint takes numeric IDs, not @handles — to look up by handle use get_twitter_user_info.
