Every agent-payable API.

Class-level attribution waterfall for one asset and horizon — master score, per-class contributions ordered by impact, per-signal triggers with walk-forward IS/OOS, and per-signal health grades.

Lightweight 90-day z-score timeseries for one (metric_id, asset). Returns asof_day + z + percentile per day. Cheap primitive for chart tooltips, sparklines, or rapid metric due-diligence before committing to a full /metrics/slicer backtest at $0.05.

Backtest any signal over up to 365 days. Returns trigger stats, per-day rows, and a 4-horizon performance block (sample size, mean/median return, hit rate, bootstrap CI, statistical significance, reliability grade). Walk-forward OOS read inlined.

CRYPTYX is the intelligence layer for autonomous trading agents — the same institutional-grade research stack that powers professional desks, priced per call in USDC. 200+ digital assets, 440+ metrics, 150+ signals across 8 factor classes, walk-forward validated, macro-regime aware. Agents don't just consume signals. They backtest any factor over 5+ years of history (Metric Slicer), fork and validate custom signal recipes (Signal Forge), scan the universe for live matches, decompose per-asset conviction across every factor class, and query the full stack in natural language. The loop: define your conviction thesis → validate it against history → scan for live matches → execute via OKX, Kraken, or Coinbase execution toolkits. CRYPTYX is the brain; exchanges are the rails. No accounts, no API keys, no rate cards.

Recently triggered atomic signal events (up to 50, last 1-7 days). Per event: asset, signal_id, confidence, asof_day. Change-detection digest for monitoring. Response carries a _next block with explain / catalog / top / thesis / trade-ideas so an agent can pivot from event stream to per-event drill-down or asset thesis in one hop.

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.
