CRYPTYX Cross-Window Z-Score Differential Trigger
x402
CRYPTYX Cross-Window Z-Score Differential Trigger is a paid API for AI agents from cryptyx.ai, paid per call via x402, $0.05/call, status unknown (last checked 2026-10-22).
Fires a trigger signal when the z-score differential between two metrics (e.g. short-window vs long-window realized volatility) crosses a user-defined threshold for a given crypto asset.

How this service works
Cross-window z-score differential trigger — the generalized crossover primitive. Pass two metric_ids (typically same factor at different windows, e.g. VOL_RV_7D vs VOL_RV_30D) and a threshold. Fires on the delta z(a) − z(b). Same institutional envelope. Applies across every factor family: TR, VOL, FLOW, FUT, OB, CORR. Backtests run over the CRYPTYX 200+ tracked digital assets — BTC, ETH, SOL, top-cap + long-tail coverage.
Output
Returns whether the trigger fired (true/false) based on whether z(metric_a) − z(metric_b) satisfies the operator and threshold condition for the specified asset and horizon, along with the computed differential value and context metadata.
Example use cases
Volatility regime crossover alert for BTC
“Tell me if BTC is in a short-term volatility spike — fire the CRYPTYX z-differential trigger when the 7-day realized vol z-score exceeds the 30-day realized vol z-score by more than 1 sigma over a 14-day horizon.”
ETH flow factor divergence detection
“Check CRYPTYX for ETH: trigger a signal if the z-score of FLOW_7D minus the z-score of FLOW_30D is above 2.0, using operator 'gt' and a 30-day horizon.”
Altcoin momentum crossover screening
“For SOL, use the CRYPTYX z-differential trigger to check if the short-window momentum factor z-score has crossed below the long-window z-score by more than 1.2 — use 'lt' operator with a 14-day horizon.”

Endpoint
GEThttps://cryptyx.ai/api/triggers/z-differential?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to detect crossover or divergence events between two CRYPTYX factor metrics at different windows for a specific digital asset — especially for volatility, flow, order book, correlation, or futures factor families. Prefer this over single-metric threshold triggers when the trading signal is fundamentally about the spread or acceleration between short- and long-window z-scores, not an absolute level.
Side effects
- Invalid or unrecognized metric_id returns an error indicating the metric is not tracked
- Unsupported asset symbol results in a 400-level error
- Invalid operator string (not in allowed enum) causes a validation error
- Threshold not a number causes schema validation failure
- Horizon value outside allowed set ('7d','14d','30d') returns an error
- Insufficient historical data for a long-tail asset may result in a null or low-confidence trigger result
