What would be a fair price for a correct score in basketball?

Let's say NBA, regular time, no OT, two broadly evenly matched teams separated by home advantage, say home team 1.5, away team 3 on the moneyline. Over/under total points is 225.5.

What price do you think correct scores would be generally available at? And what price do you think the shortest price would be, so in the example above a highly likely scoreline would be Home 116-110 Away, what would be fair odds for a scoreline like that in this scenario?

Does anyone know anywhere that does correct score betting, or good approximations of it, the only thing I've seen are winning margin type bets, but you can't bolt other match attributes to them.
