Use get_problem when you already know the titleSlug; use this to browse or discover problems.get_user_profileRetrieves any user's public profile by username (read-only, no auth). Returns ranking, avatar, bio, submission stats, and platform-specific progress. Use this to look up other users or public stats. Use get_user_status (requires auth) instead to verify the current session user's login state—not for looking up arbitrary users.get_recent_submissionsRetrieves a user's recent submission history on LeetCode Global (read-only, no auth). Includes both accepted and failed submissions. Global only—not available on CN. Use get_recent_ac_submissions for accepted-only results, or get_all_submissions (auth, current user) for paginated full history with filters.get_recent_ac_submissionsRetrieves a user's recent accepted (AC) submissions (read-only, no auth).
