Don't know what to make of the fact that they use the phrase "get you rich" liberally in their API docs. Check out how the financing works"

"In gambling, the house must have enough money on hand to cover all the bets currently in play. This amount limits the number of current users and the amount they’re risking. Betable can provide the house’s backing or you, the game creator can be the house. If Betable provides the backing of the house, Betable does a 70% / 30% revenue share in favor of Betable because it is taking all of the risk instead of the normal 50% / 50% split."
