## 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 finance-toon-haus-7f929e2f
```

Example prompt: Pull up the full options chain for TSLA — I want to see the implied volatility, volume, and open interest across all strikes and expirations.

## When to prefer this

Use this endpoint when you need structured options chain data including IV, volume, and OI for a specific stock — ideal for options traders, volatility analysis, or scanning for unusual options activity. Prefer this over general market data endpoints when derivatives data is specifically required.

## Known failure modes

- Invalid or unknown ticker symbol returns empty or error response
- Ticker has no listed options (e.g. OTC stocks) returns no data
- Market closed or data delay may cause stale IV/volume figures
- Rate limiting or payment failure returns 402 or 429 error
- Network timeout for tickers with very large options chains
