Authorizations

Authorization
string
header
required

Skylit API key in the Authorization header (Authorization: Bearer fs_live_<key>). X-API-Key is also accepted.

Path Parameters

symbol
string
required

OPRA option symbol in URL-safe form: {ticker}__{YYMMDD}{C|P}{strike×1000, 8 digits} — the ticker and the 15-character contract block are joined by a double underscore (__). For example, an AAPL $250 call expiring 2026-01-17 is AAPL__260117C00250000. (A space-padded 21-char OCC form such as AAPL 260117C00250000 is also accepted on some endpoints, but the __ form is canonical and works across all contract routes.)

Example:

"SPY__250516C00580000"
