Constituents

API QuantAPI Developer

The listings in a stock set on a single date: every constituent of a market index, or of one of your own universes.

This API returns data for multiple stocks — every constituent of a market index, or of one of your own universes — for the specified date.

Use it to read back what a bulk request covers before you make it, or to keep your own copy of an index's membership. The indices you can name are listed at /api/v11/reference/indices/list/.

Available Data Points:

  • Date: The specific date for which the data is retrieved (YYYY-MM-DD format).
  • Exchange Symbol: Symbol of the exchange where the security trades.
  • Ticker: The ticker symbol associated with the security.
  • Company Name: The name of the company issuing the security.
  • Ortex Company ID: Unique id for a company.
  • Ortex Security ID: Unique id for a security issued by a company.
  • Ortex Tradable Item ID: Unique id for a listing of a security.

Which listings are returned

A listing is returned when it was listed on the date (today, when date is omitted) and has both a ticker and an exchange symbol, so every row can be named on the stock endpoints as /stock/{exchangeSymbol}/{ticker}/ or /stock/tid/{ortexTid}/. On a past date a listing delisted since is still returned, so a historical list is not survivorship-biased. The identifiers are each listing's current ones; ortexTid is the stable key across dates.

Try it out! You can test the API with the trial key TEST. Simply include it in your request headers; either here, or add the header "Ortex-Api-Key": "TEST" to your http request.

Trial key restrictions: Trial keys may be limited to a specific date range and set of regions. Requests outside the allowed regions or entirely outside the allowed date range are rejected; a date window that partially overlaps the allowed range is trimmed to it, reported in meta.restriction.

Query Params
string

The ORTEX index identifier used by this endpoint. Return one row per constituent of this market index, as of the requested date. Pick one from the examples, or type another ORTEX index identifier; the full list, with each index's name, country and constituent count, is GET /api/v11/reference/indices/list/. Matching ignores case, so us500 and US500 are the same index. Supply exactly one of 'index' or 'universe' — sending both, or neither, returns 400 invalidSelection. An unrecognized index identifier returns 404 indexNotFound. Membership is point-in-time: a date before the index's membership history starts returns an empty page with emptyReason requestedRangeOutsideAvailableData, never today's constituents.

string

Return one row per constituent of one of your own universes, matched case-insensitively by name. Supply exactly one of 'index' or 'universe' — sending both, or neither, returns 400 invalidSelection. A name you do not own, or that does not exist, returns 404 universeNotFound. On a Quant key, a universe holding more than 250 constituents returns 409 universeSizeExceeded; nothing in it is changed. Manage your universes at /api/v11/universes/.

date

The single date to return data for (defaults to the latest available). Format: YYYY-MM-DD.

integer

Page number within the paginated result set. Must be >= 1. Defaults to 1.

Number of rows per page. The default and the maximum allowed depend on the API tier; a value above the tier maximum is rejected with 400 invalidPageSize.
