Intraday chart bars for a contract

GEThttps://flow-api.skylit.ai/v1/contract/{symbol}/chart

Time-bucketed bars for a single contract — granular bid/mid/ask execution split, premium and volume per side, daily cumulative totals, VWAP, and (when available) IV and 30D average baselines.

Authorization

Authorization: Bearer <your API key>

Required. A missing header returns 401; an invalid, revoked or expired key returns 403.

Path parameters

  • symbolstringrequired

    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.)

Query parameters

    Trailing window — {N}D where N is 1–365 (e.g. 1D, 7D).

  • bucketstringrequired
