KalshiYes/no books and settlement for every sports market.

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

Injury webhooks
The line moves on the wire
Every big pre-game move starts in the injury report. ScoreTape watches the report for you — across NFL, NBA, MLB, NHL, WNBA, and the college leagues — and fires a signed webhook the moment a status flips.
- Pushed within seconds of detection — league-wide sweeps every 60 seconds
- HMAC-signed payloads, with league and status filters per subscription
- The full change-log is archived — replay any report, or any single player's history
Coverage
Every league the markets trade
Each tile shows exactly which layers that league carries — the US majors run the full stack down to play-by-play and player props resolved to real athletes; soccer adds two decades of historical odds and extends past these tiles to 20+ competitions.

Why joined data
What it takes to trade sports prediction markets
Everything you can buy off the shelf is a silo — odds feeds without markets, scores without depth, injury news a refresh behind the line move. A strategy on Polymarket or Kalshi trades against all of them at once, so sports prediction-market data is only useful joined.
01
The join is the edge
Polymarket names a moneyline with a slug; ESPN files the same game under an event id. ScoreTape's entity-resolution layer welds the two — and keeps proving the weld by checking every settled market's winner against the real final score, with 99.96% agreement. One request, and the market, the multi-sportsbook line, the result, and the injury report arrive as one document.
02
Depth is the truth
A last price hides the spread and the size sitting at every level. ScoreTape records the live order book — both sides, every level — for sports markets on Polymarket and Kalshi, so a sports betting backtest fills against the liquidity that actually existed, not a mid-price nobody could have traded.
03
Injuries move first
Line moves start in the injury report. ScoreTape sweeps league-wide reports every 60 seconds across the US majors and pushes each status change to your webhook — HMAC-signed, filterable by league and status. The change-log is archived forward too, so you can replay the report exactly as it stood at any minute before tip-off. That history cannot be bought later.

FAQ
Common questions
The short version of what people ask before they pull their first game document.
The order books, prices, and settlements of sports markets on prediction exchanges like Polymarket and Kalshi — moneylines, spreads, totals, and props traded as binary contracts. ScoreTape records those markets tick by tick and, crucially, entity-resolves each one to the real-world game: final score, multi-sportsbook odds, and the injury report as it stood before tip-off.
