Use nfl for football or nhl for hockey. Both support universal game, team/player/venue identity, roster, standings, and odds reads. The sport-specific team, recent-game, season-stat, and injury routes have their own response shapes. NFL schedules accept week; NHL schedules accept game_type values such as preseason, regular, postseason, all-star, and other. These filters are sport-specific. A season label follows that league’s stored contract. Do not assume these leagues expose the baseball/basketball box-score, matchup, rotation, or play-by-play routes. A registered generic route can return 404 endpoint_not_for_sport for an unsupported league. Statistics and injuries also differ from NBA historical injury reports and KBO/NPB registration status. The shared Odds, Props & Signals routes use the sport’s market families. Market catalogs and public bookmaker coverage are the discovery mechanism for actual prices; league registration alone does not guarantee every prop market is populated.
