Check a bet
Check a specific sports bet against thousands of play-by-play game simulations: each leg's simulated probability, the sportsbook's implied probability, and the edge. Send the bet as plain text - teams or players, market, line, odds. A parlay in one string is graded leg by leg and priced as a whole. Call this first; nothing has to be set up, and a missing slate, an unrecognized bet, or an unsupported market comes back as a plain `status` without spending a check. It prices a bet the caller names
Today's slate
Which of MLB, WNBA, PGA, and ATP have a checkable slate right now - at least one simulated game that has not started. Pass `sport` for one; omit it for all. Free, spends no check. It is not required before `check_bet`, which reports a missing slate itself at no cost. Call it to answer "what can be checked today", or after a `no_slate` or `ungraded` result, which mean the game is not on the simulated slate rather than that the bet was worded wrong.
Checks remaining
How many bet checks the caller has left and when the next one frees up - 100 a day shared per device anonymously, 1000 an hour with a signed-in user's token. Free, spends no check. It grades nothing, so it is not a step before a check: call it when a check comes back refused for quota, or before working through a long list of bets.
