Markets & depth
Polymarket + Kalshi order books, both sides

Every feed knows the same WNBA 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.
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.
The WNBA runs the US-majors stack — order-book depth, settlement, scores, sportsbook odds, box scores, play-by-play, and the live injury wire.

"https://api.scoretape.com/v1/wnba/games?matched=true"A fast-growing market with sharp moves and tighter liquidity rewards anyone who can see the book and the report before the line settles. WNBA prediction-market data is only useful joined to the game, the box, and the injury report behind it.
Polymarket names a Liberty moneyline with a slug; ESPN files the same game under an event id. ScoreTape welds the two and verifies it against settlement (99.96% agreement across sports). One request returns the market, the books, the score, the box, and the injury report as one document.
In a thinner market, the book matters even more — a fill can move the price. ScoreTape records the live WNBA order book on Polymarket and Kalshi, both sides, every level, so a backtest sizes against real liquidity instead of a mid nobody could trade. Depth is forward-captured and cannot be backfilled.
ScoreTape sweeps the league-wide WNBA injury report every 60 seconds and fires a signed webhook the moment a status flips, filterable by team and status, with the change-log archived so you can replay exactly who was available at 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.
