One account.
The Facebook User Profile API returns a public Facebook account by ID or handle or link: name, bio and followers, in the same response format as every other SocialToAI call. One call costs 2 credits ($0.004 to $0.0067 depending on the pack); failed calls are free. Call it over HTTP or from your AI client over MCP. Last tested 2026-10-17.
