ScoreTape records the full order book of every Kalshi sports market, then welds the game's prediction markets to the final score, the sportsbook lines, and the injury report as it stood before tip-off. Served over one REST API.
Free tier, no card — every league and endpoint included.
369,000 markets across 13 leagues — every one resolved to its real-world game
every Polymarket & Kalshi sports book on record
markets, odds, results & injuries in one document
settled winners checked against final scores
every status change pushed to your webhook, signed
Every feed in sports knows the same game by a different name — a slug on Polymarket, an event id at ESPN, a rotation number at the book. ScoreTape resolves them to one record and answers a single request with everything that game was.
Order-book depth — every level, both sides, tick by tick.
Yes/no books and settlement for every sports market.
Final scores, box scores, play-by-play — plus odds from up to 15 sportsbooks.
League-wide injury reports, swept every 60 seconds.
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 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.
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.

"https://api.scoretape.com/v1/webhooks"Kalshi runs a real exchange: bids, asks, size at every level. Trading its sports markets means knowing the book — and the game behind it. Kalshi sports data is only useful joined to the result that settled it, the sportsbook line it traded against, and the injury report that moved it.
A last price hides the spread and the size sitting at every level. ScoreTape records the live order book of every Kalshi sports market — both sides, every level, tick by tick — so a backtest fills against the liquidity that actually existed, not a mid-price nobody could have traded. Depth cannot be backfilled: the tape only exists because someone was recording.
An exchange names a market with a ticker; ESPN files the same game under an event id. ScoreTape's entity-resolution layer welds prediction markets to real games — 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.
Exchange lines move on injury news before most feeds publish it. 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, so you can replay the report exactly as it stood at any minute before tip-off.
Every plan gets every league and every endpoint. You're choosing how far back the tape rolls — and how hard you can pull on it.
Seven days of tape to prove it's real.
The modeler's window — 90 days deep.
A full season on tap, live books included.
Dedicated lanes for systematic desks.
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.
