Choose this endpoint when you need structured, pre-computed options market intelligence for BTC or ETH without querying Deribit directly — especially useful for volatility regime detection, put/call sentiment analysis, or identifying max pain levels for hedging strategies. Ideal for AI agents that need lightweight, regularly-refreshed options analytics without full order book complexity.

## Known failure modes

- Deribit API unavailability causing stale or missing data
- Rate limiting if called too frequently relative to the 15-minute refresh cycle
- Payment required (402) if x402 USDC payment not included
- Empty data array if options market is closed or illiquid
- Invalid query parameters returning schema validation errors
