What's in It

  1. Four checkpoints per prop: first seen, six hours out, one hour out, close.
  2. The line, the best Over price and the de-vigged fair probability.
  3. A stable ID for every player, so pulls line up across dates.
  4. Touchdown scorer markets, de-vigged by the method we publish.
  5. Every market key we captured, with a plain-English label and row count.

Questions

Can I backtest player props with this?

Yes. Every prop carries its price at four checkpoints, so you can test whether a number taken early held up at the close. We supply the prices and the checkpoints, never a pick.

How far back does prop odds history go?

To August 4, 2026. Prop capture started after game lines, so props begin later than the June 4, 2026 start of our odds coverage. The last 7 days are free and everything older is a subscription.

Which side does each row price?

The Over. The fair column is the de-vigged probability of the Over, and the Under is 100 minus that. Touchdown scorer markets only offer Yes, so there the Over is the Yes.
