# CRYPTYX Asset Asymmetry Analysis

> CRYPTYX Asset Asymmetry Analysis is a paid API for AI agents from cryptyx.ai, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-15).

Returns return-distribution asymmetry metrics for a digital asset, including skew, tail ratio, and expected shortfall.

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-asset-asymmetry-analysis-46531402
```

Example prompt: Pull the return distribution asymmetry stats for BTC from CRYPTYX — I want to see the skew, tail ratio, and expected shortfall.

## When to prefer this

Use this endpoint when you need quantitative return-distribution asymmetry metrics for a specific crypto asset — particularly skew, tail behavior, and expected shortfall — rather than price, volume, or sentiment data. Prefer this over generic market data APIs when the use case involves risk management, portfolio construction, or evaluating downside risk exposure.

## Known failure modes

- Invalid or unrecognized asset symbol returns an error
- Symbol not covered by CRYPTYX data universe returns 404 or empty response
- Network timeout or service unavailability returns 5xx
- Missing required 'symbol' parameter returns 400 bad request

## How this service works

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).

## Output

Returns a JSON object with the asset symbol, skew value (positive = right-skewed, negative = left-skewed), tail ratio (ratio of upside to downside tail extremity), and expected shortfall (average loss in the worst-case scenarios, expressed as a negative decimal).
