Get Crypto Prediction Markets Historical

Tick-by-tick replay of Kalshi crypto prediction markets.

Every poll snapshot we captured is preserved here. The collector polls each open market every ~5 s, so a one-hour replay returns ~720 rows per market.

The archive runs from 2026-05-13 and holds two assets: BTC (price_at_or_above, price_range) and ETH (price_at_or_above, other). ETH is reachable here even though it is no longer live. A combination we have never carried returns 404 with no credit charged; a range we simply have no rows for returns an empty snapshots array, because coverage is measured over the archive and not over your requested window. Provide market_ticker to focus on one resolution slot.

Cost: 2 credits. Replay depth is bounded by your plan's historical window; an explicit from before it returns 403 HISTORICAL_LIMIT.
