The product
One Golf game, one document
Every feed knows the same Golf game by a different name — a slug on Polymarket, an event id at ESPN, a ticker on the exchange. ScoreTape resolves them to one record and answers a single request with everything that game was.
PolymarketOrder-book depth — every level on both sides, captured as complete ladders.
KalshiYes/no books and settlement for every sports market.
ESPN
Official tournament results by player — field finishing order, with winner flags.

Market depth
Backtest against the book, not the headline price
A fill has a cost the last trade never shows. ScoreTape records the live order book for sports markets on Polymarket and Kalshi, so your strategy sizes against the liquidity that actually existed at that moment.
- Every level, both sides — not a last price or a mid nobody could trade
- Forward-captured continuously; order-book history cannot be backfilled
- Replayable: snapshot time-series per outcome token via one endpoint

Why joined data
What it takes to model the golf prediction markets
A golf outright is a wide-field market that resolves over four rounds, and a make-the-cut market turns on a single putt. Golf prediction-market data is only useful joined to the tournament it settled on and the book behind the price.
01
Resolved by player
ScoreTape resolves every Polymarket and Kalshi golf market — outright winner, top-10, make-the-cut, head-to-head — to the official tournament result by player, with winner flags, and verifies it against settlement. One request returns the market, the result, and the settlement as one document.
02
Depth on a wide field
An outright market prices a hundred-plus runners, and the book is the only honest picture of each. ScoreTape records the live golf order book on Polymarket and Kalshi — both sides, every level — so a backtest fills against the liquidity that actually existed through the weekend, not a last price. Depth is forward-captured and cannot be backfilled.
03
The majors and the Tour
ScoreTape carries the majors and the regular PGA Tour board, each market resolved to its real tournament. ESPN does not retain pre-tournament sportsbook odds for golf, so the join here is market depth plus the official result — no sportsbook line layer.
