Tools: check_bet get_slate get_usage
check_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 unsupport params: bet* |
get_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 simulat params: sport |
get_usage | 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. params: none |

The grade measures how the tool definitions fit model providers (token cost, schema compatibility, confusable names) as scored by the ToolFit engine at the time of the listing. JSON: append .json.
