Per-strike IV at the latest snapshot for a single expiry.

Resolves `expiry` to a concrete chain slice (nearest upcoming expiry if omitted). Calls and puts are distinct rows so clients can plot smile curves side-by-side.

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, expiry, points: Array<{ expiry, strike, optionType, markIv }> }

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/iv"

{ "data": { "underlying": "BTC", "expiry": "25APR25", "points": [] }, "meta": { "total": 0 } }
