Get Crypto Prediction Markets
Latest snapshot of every open Kalshi crypto prediction market for the requested asset.
What is currently collected is BTC price ladders: price_at_or_above (one contract per strike, e.g. KXBTCD-26AUG0117-T53499.99, "Bitcoin price on Aug 1, 2026?") and price_range. ETH is in the archive but stopped writing on 2026-07-30, so it is served by the historical endpoint and not by this one. Ask for a combination outside the window this endpoint queries and you get a 404 naming what is live, with no credit charged, rather than a billed empty array.
Each row shows the latest yes/no bid/ask + mid-market implied probability + volume + open interest. Use the historical endpoint (/v1/historical/prediction-markets/crypto/{asset}) for replay, and for any asset that is in the archive but not currently live.
Cost: 1 credit. Refreshes within ~5s of the underlying collector poll.
