From a free key to a working prop model

Six steps, in the order that saves the most time, each with the page that does it. Most people get from step one to a first evaluation in an afternoon.

The steps

  1. Get a free key. Sign up, then create a key under Keys. Free reads every endpoint five minutes behind, which is fine for building. Sign up.
  2. Read five props. Run the starter client or the playground to see the shape of a prop: line, both prices, fair price and move summary. Starter kit.
  3. Pull graded history. Graded results give closing line against the box score; per-prop history gives every move before the start. Graded examples.
  4. Build features from movement. Line moves, price moves and the fair price at open and close. Most of the movement is in price, not line. Movement study.
  5. Fit, then beat the market. Evaluate against the closing fair price, split by time, and measure closing line value on the bets you would make. The Python guide.
  6. Go live. Switch to a paid plan for real-time lines, then follow the change feed or stream instead of polling the board. Pricing.
