## 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 orchard-data-vix-endpoint-e5b48ceb
```

Example prompt: What is the VIX right now — give me the current level, yesterday's close, and how much it has moved.

## When to prefer this

Choose this endpoint when an agent needs a lightweight, pay-per-call VIX data point without committing to a subscription, especially in agentic workflows that need real-time market volatility context on demand. Ideal for low-frequency checks where a $0.001 micropayment per call is economical and x402/USDC payments are supported.

## Known failure modes

- Payment failure via x402 if USDC balance is insufficient — returns 402 Payment Required
- Market data unavailable outside trading hours may return stale or null values
- Malformed request parameters return an error response
- Network timeouts on the Cloudflare Worker may return 503
