Search Facebook groups
Search Facebook groups by keyword. Returns groupId, name, url, privacy, members, postsPerDay. Results are infinite-scroll, capped by limit.
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.
List Facebook feed posts
List posts from a Facebook group or page feed (pass its full URL). Returns per post postId, url, author, authorUrl, reactions, comments, shares, createdTime and text. Counts are the site's displayed strings (e.g. "1,2 k"); the feed is a capped sample (by limit) in the default relevance order, not strict reverse-chronological.
