How this endpoint behaves

Header: x-api-key required.

Parameters:

slug: required CS2 tournament slug from bo3-tournaments, for example pgl-masters-bucharest-2026.

Notable response behavior:

Each row has map, games, rounds, ct_round_wins, t_round_wins, ct_win_percent, picked_maps and banned_maps. The picked and banned counts are zero at events where BO3.gg does not record vetoes.
The upstream returns the whole event and ignores stage filters, so there is no stage parameter. An unknown slug, or an event with no maps played yet, returns 404. Cached for up to ten minutes.
