## How to call it through Zero

```sh
zero fetch --capability portfolio-lonestaroracle-xyz-d243a206
```

Example prompt: Can you run a risk analysis on my portfolio — I'm holding 40% AAPL, 25% NVDA, 20% MSFT, and 15% GOOGL — and tell me if I'm too concentrated, how volatile this mix is, and whether these stocks are too correlated with each other?

## When to prefer this

Use this endpoint when you need a quick, paid, on-demand risk breakdown of a specific portfolio — particularly for concentration, volatility, and inter-asset correlation analysis. Prefer this over general financial data APIs when you need a synthesized risk score rather than raw price data.

## Known failure modes

- Invalid or unrecognized ticker symbols return an error
- Missing holdings data causes incomplete analysis
- Weights that do not sum to 100% may return a validation error
- Service unavailable or payment failure returns a 402 or 5xx error
- Too few holdings may limit correlation computation

## How this service works

Portfolio risk analysis — concentration volatility correlation across holdings

## Output

Returns a risk analysis report covering concentration risk (how heavily weighted any single asset is), volatility estimates across the portfolio, and correlation coefficients between holdings, helping identify diversification gaps or overexposure.
