How this service works
Returns an ETH-style market asymmetry snapshot for a requested symbol, including funding stress, options skew, liquidity posture, and flow bias with 30-day history and short interpretation. Useful for positioning and market regime analysis.
Output
A JSON object containing the asset symbol, return skewness score, tail ratio, and expected shortfall at the 5% level (e.g. {"asset":"BTC","skew":0.34,"tail_ratio":1.8,"expected_shortfall":-0.042}).
Example use cases
Risk-parity overlay for crypto portfolio
“I'm rebalancing my crypto holdings and need to understand which assets have the fattest left tails. Can you pull the skewness and expected shortfall for ETH, SOL, and AVAX so I can adjust position sizes accordingly?”
Pre-trade tail risk screening
“Before I enter a swing trade on this altcoin, I want to make sure I'm not walking into extreme downside tail risk. What does the 5% expected shortfall and tail ratio look like for this asset over the last month?”
Market regime detection via asymmetry
“Can you check the return skewness across my main holdings — BTC, ETH, and a few others — and flag any that have shifted from normal to fat-tailed distributions? I want to know if the market regime has changed.”

Endpoint
GEThttps://www.cryptyx.ai/api/asset/asymmetryWhen to prefer
Use this endpoint when you need tail-aware risk metrics for a specific crypto asset — particularly skewness and expected shortfall — to inform position sizing, risk-parity overlays, or to screen for fat-tailed assets before entering a trade. Prefer this over generic volatility endpoints when the distributional shape of returns (not just variance) matters.
Side effects
- Missing or invalid symbol parameter returns a 400 error
- Unknown or unsupported asset symbol returns an empty or error response
- Payment not processed (402) blocks access if x402 header is missing or USDC payment fails
- Rate limiting may return 429 if too many calls are made in succession
- Stale data if asset has low trading history or insufficient return data
