## 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 adh-processed-fear-index-cross-asset-panic-thermometer-1cc735de
```

Example prompt: What's the current cross-asset fear and greed reading — give me the VIX, volatility breakdown for gold, stocks, and crypto, and the overall panic thermometer score with an interpretation of what it means for risk assets.

## When to prefer this

Choose this endpoint when you need a pre-processed, multi-asset fear/greed composite rather than raw VIX data alone. It is ideal for AI agents that need a single authoritative sentiment score with interpretation, without building their own volatility aggregation pipeline. Prefer it over raw market data feeds when you want cross-asset context (gold + equities + crypto in one call) and a narrative interpretation included in the payload. At $0.01 USDC via x402, it is cost-effective for frequent polling in automated workflows.

## Known failure modes

- Stale data if upstream volatility sources are delayed — check collected_at timestamp
- 402 Payment Required if x402 payment header is missing or USDC balance is insufficient
- Network timeout if agentdatum.com servers are under load
- Empty or partial response if one of the 239 underlying sources is temporarily unavailable
- Rate limiting if too many requests are made in a short window
