Search Facebook groups
Search Facebook groups by keyword. Returns groupId, name, url, privacy, members, postsPerDay. Results are infinite-scroll, capped by limit.
Join Facebook group
Join a Facebook group by id/slug. Returns status (joined / pending / already_member) and name. Pending means a private-group request was sent, not membership.
Get Facebook profile info
Get header and intro info for a Facebook profile or page (pass a URL or a bare id/username). Returns the type (profile or page), the name, friends, likes and follower counts as displayed, mutual friends, and the intro lines — bio plus city, work and education for people, or the description for pages. Counts come back as the strings Facebook shows (e.g. "11 K") and intro lines are returned as they appear, not sorted into city, work or school fields. Works in either the French or the English interface. An id or username Facebook will not serve returns a clear error rather than an empty record.
