## When to prefer this

Use this endpoint when you need structured implied volatility surface data for a specific crypto asset, including IV, delta, expiry, and strike dimensions. Prefer this over generic price feeds when performing options pricing, hedging analysis, or volatility trading on digital assets.

## Known failure modes

- Invalid or missing asset parameter returns 400-level error
- Payment failure (x402) prevents data retrieval
- Stale or unavailable market data may result in incomplete surface
- Rate limiting or quota exceeded returns 429 error
