  • Grade any MLB, WNBA, PGA or ATP bet against thousands of play-by-play game simulations — true win probability, implied probability, and edge for every leg. Prices come from a purpose-built game simulator, not from copying sportsbook lines. A model answering from general baseball knowledge produces a fluent, confident, wrong number; this server returns a probability computed from simulations of the actual game — today's lineups, today's injuries, tonight's weather. Most slips it grades come back Negative EV. **Tools** - `check_bet` — Grade a bet from plain text ("Aaron Judge over 1.5 total bases -120"). Returns each leg's simulated probability vs the implied odds and the resulting edge. - `get_slate` — Whether a checkable slate exists right now, per live sport. - `get_usage` — Checks remaining and when the next frees up.
