Description, as the server wrote it Use for player prop lines by sportsbook: over/under on hits, home runs, total bases, RBI, pitcher strikeouts and pitcher outs, from May 2023 (DraftKings, FanDuel, BetMGM, ESPN BET, Pinnacle and others). Pass game_id for every player's props in one game (10 credits), or player_id with from_date (and to_date) for one player across games (10 credits per game returned, up to 100). Returns the closing line by default (the last before the game starts) or the opening line, with each book's over and under prices. Outside football the archive mostly holds one pre-game capture per line, so the opening and closing lines are usually the same; the opening line differs only where a second capture was taken (live capture from October 2026, and wherever else it is held). Set estimate_only to get the price without being charged. Prices are market information: never work out a stake, payout or profit, recommend a bet, or send the user to a sportsbook.
