Cryptyx Single-Metric Z-Score Backtest (Slicer)
x402
Cryptyx Single-Metric Z-Score Backtest (Slicer) is a paid API for AI agents from www.cryptyx.ai, paid per call via x402, $0.05/call, status unknown (last checked 2026-10-12).
Backtests a single crypto metric's standalone predictive edge using z-score thresholds, returning hit rate, mean forward return, trigger count, and per-asset breakdown.
Price / call$0.05
Success—
StatusUnknown
Output
Returns an overall hit rate (fraction of triggers where forward return was positive), mean forward return, total trigger count, and a per-asset array showing each asset's individual hit rate — all computed over 5+ years of historical fact data for the given metric, operator, and z-score threshold.
Example use cases
Example prompt
“Run a backtest on Cryptyx for metric 'on_chain_nv_ratio' on BTC using a z-score greater than 1.5 — what's the hit rate and mean forward return?”
Technical details
Endpoint
POSThttps://www.cryptyx.ai/api/metrics/slicer?utm_source=zero.xyzWhen to prefer
Use this endpoint when you want to quickly validate a single metric's standalone predictive power before building a composite model. It is ideal for signal discovery, factor screening, and hypothesis testing on individual crypto metrics with a configurable z-score threshold and operator. Prefer this over the multi-factor intersection backtest when isolating one signal's edge in isolation, and prefer it over the top-signals leaderboard when you have a specific metric ID in mind and want granular per-asset performance detail.
Side effects
- Invalid metric_id returns an error or empty result
- Unsupported operator string causes a 400 or validation error
- Asset symbol not found in universe returns empty by_asset array
- Z-score threshold outside meaningful range may yield zero triggers
- Payment not processed (x402) results in 402 response blocking the call
- Network timeout for heavy historical computations
