## When to prefer this

Use this endpoint when you need a standardized, contextualized implied volatility risk signal for BTC or ETH specifically from the Deribit options order book — the most liquid crypto derivatives venue. Prefer this over raw price feeds when you need options-market-derived fear/uncertainty metrics with historical percentile context. Best for risk dashboards, trading signals, and portfolio volatility assessment.

## Known failure modes

- Invalid asset value (not BTC or ETH) returns a 400 or validation error
- Invalid window value (not 7d, 30d, or 90d) returns a 400 or validation error
- Deribit upstream unavailable causes a 502 or 503 error
- Payment not provided or rejected returns a 402 Payment Required
- Stale cache data if Deribit candle feed is delayed
