## 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 market-intelligence-api-portfolio-risk-check-56833b9e -d '<json body>'
```

Example prompt: Can you run a full risk check on my portfolio — I'm holding $5,000 in BTCUSD, $3,000 in ETHUSD, $2,000 in NVDA, and $1,500 in TSLA, plus a $500 position in the on-chain token at address 0xabc...123 on Base — and tell me the VaR, concentration issues, correlations, any macro events in the next 24 hours, and what trades to make?

## When to prefer this

Choose this endpoint when you need a comprehensive, multi-dimensional risk snapshot of a mixed portfolio (equities + crypto + on-chain tokens) in a single low-cost call. It is ideal for pre-trade portfolio reviews, daily risk monitoring, or before answering a user question about overall portfolio health. Prefer it over single-asset endpoints when you need cross-asset correlation and concentration analysis alongside individual signals and macro event awareness.

## Known failure modes

- Exceeding 15 positions or 5 on-chain tokens returns a validation error
- Invalid or unrecognized symbol (e.g. misspelled ticker) may result in partial results or error for that position
- Missing both quantity and valueUsd for a position causes a schema validation failure
- Unsupported blockchain chain returns an enum validation error
- Payment not completed (x402 protocol) results in a 402 Payment Required response
- Stale or illiquid on-chain token data may reduce VaR accuracy

## How this service works

Crypto and stock portfolio risk check ($0.25): POST up to 15 positions (symbol + valueUsd or quantity) and 5 on-chain tokens; get concentration, correlations, volatility and one-day 95% VaR from hourly on-chain data, the current decision per symbol, token risk verdicts, macro events in the next 24h and flags with what to fix. Use to review holdings in one call.

## Output

Returns a structured JSON object with: portfolio-level concentration score, pairwise correlation matrix, volatility measures, 1-day 95% VaR computed from hourly on-chain data, a current buy/hold/sell decision for each equity/crypto symbol, individual risk verdicts for each on-chain token, a list of macro events expected in the next 24 hours, and prioritized flags indicating what to fix in the portfolio.
