# Get Daily Aggregate Summaries

`GET /v1/market-data/daily-summary`

## Request

- Base URL: `https://api.clearstreet.com`
- URL: `https://api.clearstreet.com/v1/market-data/daily-summary`
- Auth: HTTP bearer

> **Deprecated.**

**Deprecated**: use `GET /market-data/snapshot` instead, which now reports
the same open/high/low/volume/open-interest fields under `session` and
top-level `open_interest`.

Returns the most recent open, high, low, volume (OHLV) and current price
for the requested instruments.

Response contract: every request returns one row per **unique** resolved
`instrument_id`, in first-seen request order. Resolvable ids with no
available data come back with `symbol` populated but market-data fields
`null`. Ids that fail to resolve are omitted from `data` and reported in
`error` instead (see the 207/404 responses below).

## Query parameters

- `instrument_ids` string, required

## Response `200`

Daily aggregate summaries

- object
  - `error` ApiError: A direct mapping of tonic::Status, for use in HTTP responses.
    - `code` integer, required: The error code is used to identify the nature of the error. It corresponds to an HTTP status code.
    - `details` object[]
    - `message` string, required: A human-readable message providing more details about the error.
  - `metadata` ResponseMetadata, required: Metadata for the response. This will always contain a request ID which can be used to identify the request to Clear Street for tracing, and optionally may include pagination data.
    - `next_page_token` string, byte, nullable: Base64URL-encoded pagination token
    - `page_number` integer, nullable: Pagination. Included if this was a GET (list) response
    - `previous_page_token` string, byte, nullable: Base64URL-encoded pagination token
    - `request_id` string, required: A unique ID for this request, generated upon ingestion of the request.
    - `total_items` integer, nullable: Total number of items available (not just in this page).
    - `total_pages` integer, nullable: Total number of pages available.

    - `low` string, nullable: Session low. When a null/undefined value is observed, it indicates that there is no available data.
    - `not_applicable` boolean: `true` when the instrument type has no daily summary by definition (e.g. an index). Distinguishes an intentional N/A from OHLV that is merely not loaded yet. `false` for instruments that can have a summary.
    - `open` string, nullable: Opening price for the session. When a null/undefined value is observed, it indicates that there is no available data.
    - `open_interest` integer, nullable: Open interest (outstanding contracts). Populated for options only; `None` for equities and indices. When a null/undefined value is observed, it indicates that there is no available data.
    - `symbol` string, nullable: Display symbol for the security. `None` for unresolvable IDs. When a null/undefined value is observed, it indicates that there is no available data.
    - `trade_date` string, date, nullable: Session date the OHLV represents, US/Eastern. When a null/undefined value is observed, it indicates that there is no available data.
