Every feed knows the same NHL game by a different name — a slug on Polymarket, an event id at ESPN, a ticker on the exchange. DepthFeed 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
Final scores, box scores, play-by-play — plus multi-book moneyline, spread, and total odds.
Injury wire

Market depth
Backtest against the book, not the headline price
A fill has a cost the last trade never shows. DepthFeed 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 NHL prediction markets
A hockey market turns on the starting goalie, the puck line, and a confirmation that can land minutes before puck drop. NHL prediction-market data is only useful joined to the game, the box, and the report behind the price.
01
The join is the edge
Polymarket names an Oilers moneyline with a slug; ESPN files the same game under an event id. DepthFeed welds the two and verifies it against settlement — settled winners agree with the real result in 99.96% of checked games. One request returns the market, the books, the score, and the injury report as one document.
02
Depth, both sides
DepthFeed records the live NHL order book on Polymarket and Kalshi — both sides, every level, continuously — so a backtest sizes against the liquidity that actually existed, not the last trade. Depth and puck-line movement are forward-captured and cannot be backfilled once the game is final.
03
Goalie news moves the line
The biggest pre-game NHL move is a starting-goalie change. DepthFeed sweeps the league-wide report every 60 seconds and fires a signed webhook on every status flip, filterable by team and status, with the full change-log archived so you can replay exactly who was confirmed in net at puck drop.
