Greeks snapshot — every strike in the latest chain.

Delta, gamma, vega, theta per instrument. Nulls are the norm — Deribit's `book_summary` endpoint doesn't populate Greeks; they appear only when the worker has back-filled via `public/ticker` (usually ATM ± N strikes). Pass `?instrument=BTC-27JUN25-70000-C` to fetch a single row.

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, greeks: GreeksRow[] } | { underlying, instrument: GreeksRow }

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/greeks?instrument=BTC-27JUN25-70000-C"

{ "data": { "underlying": "BTC", "instrument": { "instrumentName": "BTC-27JUN25-70000-C", "expiry": "27JUN25", "strike": 70000, "optionType": "C", "delta": 0.52, "gamma": 0.00013, "vega": 42.1, "theta": -18.7, "markIv": 62, "underlyingPrice": 69800 } } }

Notes

• Most rows have null Greeks. The worker only back-fills the ATM band via per-instrument ticker calls.
