Pull Pinnacle's no-vig probability
Pinnacle is widely regarded as the sharpest sportsbook in the world. They accept large action from professional bettors and adjust quickly. Their lines incorporate sharp money — making their no-vig (devigged) probability the closest thing to true probability the market has.
We pull Pinnacle's live odds for every supported player prop on a refresh cycle and apply multiplicative devig to get the implied true probability for each side.
