CRYPTYX · Asset Asymmetry
cryptyx.ai
Cross-class positioning panels per asset — futures funding stress, options 1M risk-reversal skew, order-book imbalance, and 7-day taker buy/sell ratio. Each panel: current z, percentile, 30-day sparkline, one-line narrative. Response carries a _next block with active-signals / thesis / regime-context / top-setups / peer-cluster so an agent can go from positioning read to per-asset conviction, historical edge, or basket construction without leaving the flow. Coverage: pass any asset in the CRYPTYX 200+ tracked universe (BTC, ETH, SOL, top-cap + long-tail).
