Fetch all player props for one game identified by eventId. Read-only. No side effects. Requires an API key; rate-limited per your tier. Returns: { eventId, sport, homeTeam, awayTeam, startTime, props: Array<{ player, stat, line, overOdds, underOdds, bookCount, gameState?, flashProjection? }>, sources: string[], fetchedAt, delayed }. flashProjection (present for modeled markets, CoD + MLB today, when available) is { value, sampleN, method, marketKey }, the Flash season-baseline projection, never fabricated. overOdds and underOdds are American-format integers (e.g. -110, +115); null when odds are not available. The stats parameter filters to specific markets (e.g. "points,rebounds" for NBA, "strikeouts,hits_allowed" for MLB). Typical workflow: (1) call list_games to get eventIds, (2) call get_game_props with the eventId. Alternatively, call find_game with team names to resolve the eventId when you know the matchup. Event ids are prefixed ud- (Underdog Fantasy source) or bv- (Bovada source). Returns an error when the event id is not found, the game has ended with no active props, or lines have not been posted yet. When to use: when you have an eventId and want all props for that specific game. When not to use: use scan_props instead when you want a cross-game market view (e.g. all strikeout props today). Use find_player_props when you know the player name but not which game they are in.
