# One-minute intraday bars with per-minute options flow

`GET /api/v1/cboe/intraday/{symbol}`

The latest session's one-minute bars for any optionable US symbol: price OHLC plus PER-MINUTE options flow (calls_volume / puts_volume / total_options_volume) and, for stocks, the stock volume - an intraday options-flow signal available nowhere else on this API. Symbols follow the /options convention: underscore prefix for indices (_VIX, _SPX), plain ticker for stocks (AAPL). Bar times are exchange-local (US/Eastern). Prices published as 0.0 while volume flows are placeholders and served null. 15-minute delayed data; unknown symbols answer 404.

## Path parameters

- `symbol` string, required — Symbol; underscore prefix for indices.

## Response `200`

One session of minute bars with options flow.

- EnvelopeCboeIntradayData
  - `data` CboeIntradayData, required
    - `symbol` string, required — Requested symbol (underscore prefix for indices).
    - `updated_at` string, nullable — The source document's own update stamp.
    - `session_date` string, nullable — Trading session the bars belong to (YYYY-MM-DD).
    - `timezone` string — Bar-time zone.
    - `count` integer, required — Bars returned (~390 for a full session).
    - `bars` CboeIntradayBarV1[] — Ascending minute bars.
      - `time` string, required — Bar start, exchange-local US/Eastern (YYYY-MM-DDTHH:MM:SS).
      - `open` number, nullable — Bar open. Null when the source published a 0.0 placeholder.
      - `high` number, nullable — Bar high.
      - `low` number, nullable — Bar low.
      - `close` number, nullable — Bar close.
      - `stock_volume` integer, nullable — Stock volume in the minute (0 for indices - honest zero).
      - `calls_volume` integer, nullable — Options CALL volume in the minute.
      - `puts_volume` integer, nullable — Options PUT volume in the minute.
      - `total_options_volume` integer, nullable — Total options volume in the minute.
  - `meta` SugraMeta, required — Metadata attached to every /api/v1/* response envelope.
    - `endpoint` string, required — Requested endpoint path.
    - `data_time` string, required — ISO 8601 UTC timestamp of the source data, not of the request.
    - `response_time` string, required — ISO 8601 UTC timestamp when this response was produced.
    - `provider` string, required — API name and version.
    - `source` string, nullable — Identifier of the primary upstream source used for this response.
    - `attribution` string, nullable — Human-readable attribution mandated by an upstream source (e.g. a securities regulator or self-regulatory organization). Present only on responses whose source requires the owner and source to be clearly identified. Do not remove or alter it when using the response.
    - `fallback_used` boolean, nullable — True when the primary source failed and a fallback produced the data.
    - `fallback_chain` string[], nullable — Ordered list of sources attempted, in the order they were tried.
    - `cached` boolean, nullable — True when this response was served from the internal cache.
    - `stale` boolean, nullable — True when the cached response was returned after the upstream rate-limited or errored. Clients can use this to detect degraded data.

## Other responses

- `401` — Missing or invalid `x-api-key` header. JSON body with a stable `code` distinguishing `missing_api_key` (no header sent) from `invalid_api_key` (header sent, key not accepted); any other 401 source carries the generic `unauthorized` with its detail as `reason`. Plus `hint`. `plan` is always null on 401 - an unauthenticated request has no plan; quota exhaustion is 429, not 401.
- `422` — Validation Error
- `429` — Daily rate limit exceeded. Check `X-RateLimit-Reset` for the next window.
- `503` — Upstream source is temporarily unavailable. Retry after a short delay.
