Tools 5 found in our last check
create_ladderCreate or update the club ladder: club name and sport. Returns the join URL (the poster target) that players scan.
add_playerRegister one player by name. Returns a 6-character code and a personal URL so the player can be identified at the courts without an account.
record_matchRecord a finished match result. Identify players by name, numeric id, or 6-character code. Give the set score (sets_a, sets_b) and optionally the games.
schedule_matchPut a match on the calendar before it is played. It appears as a pending card in the standings output.
get_standingsThe current table (rank, wins, losses, set percentage) plus the single most useful match to play next. Standings are computed with a fixed rule order, so the same results always give the same table.
