Intraday chart bars for a contract

Authorization

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

• intervalstringrequired

  Trailing window — {N}D where N is 1–365 (e.g. 1D, 7D). At most 30D with an intraday bucket. Priced by range: 3 credits per started 30 days. N counts trading days (weekends and market holidays are skipped), ending with the current or latest session.

• bucketstringrequired

  Bucket size. Every bucket in the window is returned, zero-filled when nothing traded, so the response grows with window / bucket: 1min over 30D is about 11,700 bars (390 per session), a multi-megabyte response. For windows over about 20 trading days, use 5min or coarser. Retention: 1min-30min cover the last 365 days; 1d and 1w go back to 2023-03-27.

Responses

• 200

  Intraday bars for the contract.

• 400

  Request validation failed.

• 401

  Missing or invalid API key.

• 402

  The account's shared Skylit credit balance is lower than this route's cost. Top up to continue. Carries X-Credits-Remaining: 0.

• 403

  Unknown, revoked or expired API key (the gateway's forbidden), the account's API access is suspended (account_suspended) or blocked (account_blocked). Not retryable.

• 404

  Unknown ticker or contract (SYMBOL_NOT_FOUND), or no data for the requested window. Not charged.

• 429

  Either the key exceeded its requests-per-minute limit (X-RateLimit-Limit; no Retry-After, wait until X-RateLimit-Reset), or the account is over one of the API's own limits, such as the query budget (queries running at once, fresh queries per second): TOO_MANY_CONCURRENT_QUERIES or RATE_LIMITED with Retry-After. Not charged; retry after the wait.

• 500

  Unexpected server error (INTERNAL_ERROR, DATABASE_ERROR). Not charged; safe to retry with exponential backoff.

• 503

  Underlying data source temporarily unavailable, the credit balance could not be verified (credit_check_failed), or the API is paused for maintenance (api_paused, with a Retry-After header and a retry_after field in seconds). Not charged; safe to retry.

• 504

  The request did not complete within 25 seconds. Not charged; narrow the window or retry.

    Short opaque ID for log correlation.

  • nextCursorstring

    Trade feeds (/v1/flow/{ticker}, /v1/contract/{symbol}/trades): pass back as cursor with the same filters for the next page. Present only when more rows may follow.

  • nextEndTimestringdate-time

    /v1/flow/{ticker} only: the last row's exact time (RFC 3339 with nanoseconds), for end_time paging. Inclusive, so rows at that instant can repeat; nextCursor never repeats or skips.
