Deribit Volatility Index (DVOL) — current + history.

DVOL is Deribit's 30-day forward IV index. We ingest it into `sentiment_index` under `btc_dvol` / `eth_dvol`. This endpoint returns the latest reading plus a bounded history.

Path parameters

Segments of the URL path, validated server-side.

Query parameters

All query parameters are optional unless marked required.

Response shape

Always wrapped in the standard envelope. Nullable fields are explicitly marked — treat missing numeric data as a real data-source gap, not as an error.

// Wrapped in the standard envelope:
// {
//   data: /* shape below */,
//   meta?: { total?: number; limit?: number; offset?: number; ... }
// }

{ underlying, current: { value, ts } | null, history: Array<{ ts, value }> }

Example

Copy the curl, replace YOUR_KEY with a real key from your dashboard, and run.

curl -sS "http://localhost:3000/api/v1/options/BTC/dvol?limit=90"

{ "data": { "underlying": "BTC", "current": { "value": 58.4, "ts": 1744834800000 }, "history": [] }, "meta": { "total": 0, "limit": 90 } }
