Kalshi Prediction Market Data
9 endpoints covering events, markets, price history, order books, and series — structured access to Kalshi's regulated US prediction exchange with a single access token.
What is Kalshi?
Kalshi is the first CFTC-regulated prediction market exchange in the United States. Users trade Yes/No binary contracts on real-world events — from Federal Reserve rate decisions and election outcomes to Bitcoin price levels and sports results. Every contract settles to $1 (Yes wins) or $0 (No wins), making Kalshi a unique real-money signal on what the market thinks will actually happen.
Anysite's Kalshi endpoints expose the exchange's full market data: tradeable contracts with live bid/ask prices, OHLC candlestick history, order-book depth, and the trade feed — all without managing OAuth or Kalshi API credentials.
