npb and the base path /v1/npb. Choose a sidebar category
for games/live state, identities/rosters, player context, lineups/box scores,
pitch matchups, team statistics, first inning/NRFI, or pricing/history signals.
Start with /games?date=YYYY-MM-DD, then use a canonical game ID for detail,
lineup cards, box scores, matchup, NPB play-by-play, and recaps. Player
/season-stats accepts role and scope; NPB also supplies arsenals,
pitch-type results, batter versus pitcher, team batting/fielding, bullpen
projections, first-inning statistics, and umpire tendencies.
Lineup cards use the lighter season-line format. Injury reads reflect
registration/roster status. NRFI includes a nullable probability from
heuristic_v1. Read the Baseball guide before interpreting
metrics or comparing league-specific derived statistics.
Statistics and historical reads require the stats entitlement. For pricing
formats, fair probabilities, history, and settlements, see the
Odds, Props & Signals guide.
