This reference uses nfl and the base path /v1/nfl. Expand the categories for games/live state, teams/players/rosters, season statistics, and pricing/history signals. Use /games?date=YYYY-MM-DD for a schedule, then the canonical game ID for detail and live state. Team, player, venue, roster, and standings reads provide identity and competition context. The NFL-specific routes include team season statistics, recent team games, league and team injuries, and external-ID lookup. Read Football & Hockey for coverage and route differences. Statistical and historical reads require the stats entitlement. For price formats, best/fair prices, history, and settlement signals, see Odds, Props & Signals. Populated fields depend on source coverage.
