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, totalVol, callVol, putVol, putCallVol, asOf, byStrike: StrikeVolumeRow[] }
