How this service works

Professional crypto market intelligence. Real-time prices, signals, and market scoring.

Output

Returns a JSON object with portfolio-level risk metrics (VaR 95%/99%, CVaR 95%, annualized portfolio volatility, Sharpe ratio, Sortino ratio, max drawdown), a per-asset breakdown of individual volatility and drawdown, a full NxN correlation matrix for the assets, and a diversification ratio — all computed over the requested lookback window.

Example use cases

Rebalance portfolio to reduce tail risk

“I'm holding BTC, ETH, and SOL right now. Can you analyze the downside risk metrics — especially CVaR and max drawdown — so I know if my current allocation is too exposed to extreme losses? I want to see which assets are dragging down my Sortino ratio.”

Evaluate new assets before adding them

“I'm thinking about adding USDC, MATIC, and AVAX to my existing BTC-ETH portfolio. Before I commit any capital, can you run a full risk analysis showing how these new assets would change my portfolio volatility, Sharpe ratio, and the correlation matrix? I want to make sure I'm actually improving diversification.”

Monitor crypto hedge fund performance limits

“We manage three separate crypto portfolios — one is 50% BTC / 50% ETH, another is 40% SOL / 40% MATIC / 20% LINK, and the third is 70% BTC / 20% ETH / 10% DOT. Can you give me the Value-at-Risk at 95% and 99%, max drawdown, and diversification ratio for all three so I can flag any that are approaching our risk limits?”

Technical details

Endpoint

GEThttps://api.carbon-cashmere.de/v1/portfolio-risk?utm_source=zero.xyz

When to prefer

Choose this endpoint when you need institutional-grade, multi-metric portfolio risk analytics for crypto assets including VaR, CVaR, Sharpe/Sortino ratios, correlation matrix, and diversification ratio all in a single call. Prefer this over single-asset volatility endpoints when you have a multi-asset portfolio with specific weights and need a holistic risk picture including cross-asset correlations.

Side effects

Invalid coin symbol — returns error if an unrecognized ticker is provided
Wrong number of weights — weights array length must match coins array length
Weights don't sum to 1.0 — invalid portfolio specification
Fewer than 2 or more than 10 coins — outside supported range
Invalid days value — must be one of 7, 14, 30, 60, 90
Insufficient historical data for requested lookback period
