# Cryptyx Metric Slicer Scan

> Cryptyx Metric Slicer Scan is a paid API for AI agents from www.cryptyx.ai, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-13).

Scans a single metric across ~200 crypto assets and returns z-score extremes ranked by percentile, identifying outliers above or below a given threshold.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability cryptyx-metric-slicer-scan-5e52262e
```

Example prompt: Scan all ~200 crypto assets for z-score extremes on TR_TREND_STRENGTH_14D right now — show me everything above an absolute z-score of 3 using the abs_gt operator, ranked by percentile.

## When to prefer this

Use this endpoint when you need a cross-asset universe scan for a single metric — i.e., 'who across all 200 assets is extreme on X right now?' Prefer this over per-asset endpoints when you don't have a target asset in mind and want to discover outliers. Use instead of the backtest endpoint when you want live current readings rather than historical hit rates. Ideal for screening and anomaly detection workflows.

## Known failure modes

- Invalid metric_id returns 400 with metric not found error
- Invalid operator value (not in gt/lt/gte/lte/abs_gt) returns 400 validation error
- Missing required query parameters (metric_id, operator, threshold) returns 400
- Payment not included or insufficient USDC results in 402 Payment Required
- No assets exceed the threshold — returns empty extremes array with total_scanned count
- Threshold set too low floods response with near-trivial results

## How this service works

Scans a requested market metric across assets and returns the matching symbols, score statistics, and health context. Useful for filtering cross-sectional signals like rate of change, momentum, and related metrics.

## Output

Returns a ranked list of assets with z-score extremes for the specified metric, including each asset's z-score value, percentile rank, and the total number of assets scanned (typically ~200). Results are sorted by z-score magnitude so the most extreme outliers appear first.
