  description: 'Public, read-only REST API exposing Chess.com data: player profiles and stats, monthly game

    archives (JSON and PGN), clubs and members, daily and live team matches, Swiss and round-robin

    tournaments, titled-player lists, country rosters, the daily puzzle, the streamer list, and

    live leaderboards.

    at most every 12-24 hours. Clients are encouraged to send a recognizable User-Agent including a

    contact email or URL.
