## 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 synapse-market-risk-index-9779db3c
```

Example prompt: What's the current crypto market risk level? I want to know the overall risk score and whether any stablecoins are depegging right now.

## When to prefer this

Choose this endpoint when you need a fast, consolidated crypto market risk snapshot including stablecoin depeg monitoring without needing an API key. Ideal for agents making risk-gated decisions in DeFi workflows, or for dashboards that poll market health. Prefer this over individual asset feeds when you need a single composite risk score across the whole market.

## Known failure modes

- Payment not provided or insufficient USDC — returns HTTP 402
- Malformed query parameters — may return 400 or empty result
- Upstream data source unavailable — may return stale or error response
