Get Quant Market
GET/v1/cryptodata/quant/market
Whole-market regime + probability object (Pro). HMM-filtered posterior over the 6 market regimes (strong_trend_bull/bear, range_low_vol, choppy_high_vol, vol_spike, squeeze) with calibrated probability buckets for direction, volatility, liquidation risk, funding, breadth, open interest and regime transitions at the requested horizon. The market `liquidation_risk` bucket is depth-aware — driven by live order-book fragility (thin book + wide spread = higher forced-liquidation odds), not just realized volatility; the source is tagged in `explain.heads_provenance` (e.g. `depth_fragility:thin`). Includes seeded Monte Carlo tomorrow-distribution stats on the 24h horizon and a full `explain` block. Refreshed every 15 minutes from hourly bars. Market-wide and per-coin regime data (/quant/coins) are both Pro.
