## 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 cboe-vix-index-spot-quote-6bbffc56
```

Example prompt: What's the current VIX level? I want to check how volatile the market is right now.

## When to prefer this

Use this endpoint when you need a quick, low-cost ($0.01) spot check of the CBOE VIX index without setting up a full brokerage or market data subscription. Ideal for agents monitoring market sentiment, triggering volatility-based logic, or building financial dashboards. Prefer this over scraping Yahoo Finance directly since it abstracts the parsing and payment is handled via x402 micropayment protocol.

## Known failure modes

- Yahoo Finance data feed unavailable — upstream timeout or 5xx error
- Stale or delayed data if Yahoo Finance feed is lagging
- Rate limit exceeded if called too frequently
- Payment not accepted — x402 payment flow fails, returning 402 status
