ask
Ask a Betting Price Question
Ask one whole sports betting price question in plain English, the way a person would: which book pays the most for a bet, hedge math on a ticket, a parlay price, a game's board, a past result or how a line has moved. Returns a plain-sentence answer, the time the prices were scanned and a link to the matching page on theoddsgap.com. When a question could mean more than one game, it returns the choices as plain text to ask again with. Prices may have moved since the scan. Information only: it places no bets and gives no picks.

calc
Betting Calculator
Runs a betting calculation on numbers you supply: convert odds between formats, implied probability, payout on a stake, the no-vig price of two sides, hold, breakeven, a parlay of typed odds, or an arb or hedge split on typed prices. Uses only the numbers given, no market data.
