# GET /v1/owners/institutional/ticker

> Retrieve institutional managers that disclosed a position in one issuer for a selected 13F cohort

Retrieve institutional managers that disclosed a position in one issuer for a selected 13F cohort

  Audience: application and coding agent.

## Coverage and source scope

Use this issuer-centric view to identify managers that disclosed a position in one security within the selected materialized 13F cohort. Provide either the issuer ticker or issuer CIK, not a manager identifier. The response is ranked by disclosed position value and tied to its returned report date, filing date, and accessions; it is not a current cap table, complete holder roster, or real-time ownership measure. Pagination is offset-based: advance only with the returned `nextCursor` while `hasMore` is true, and read the full cohort size from `totals.holders`. Cohort availability depends on the materialized 13F read model, so preserve provenance and freshness metadata and treat a non-2xx response as unavailable data rather than an absence-of-holders conclusion. See [ownership workflows](/ownership-workflows).

## Canonical metadata

* `requestId`
* `traceparent`
* `provenance`
* `freshness`
* `materialization`

## Example response

## Agent mode

Pass `?view=agent` for a compact holder ranking. It retains the reporting cohort and each manager's name, CIK, accession number, issuer, shares, value, and rank, while dropping nonessential holder metadata.

## Give this prompt to your agent

<Prompt>
  Use SEC API GET /v1/owners/institutional/ticker to retrieve institutional managers that disclosed a position in one issuer for a selected 13F cohort. Preserve `requestId`, `traceparent`, `provenance`, `freshness`, `materialization` in the output. Return a concise markdown summary plus the exact structured payload fields that a downstream engineer or agent should keep using this result.
</Prompt>

## Failure posture

* treat non-2xx responses as contract-aware failures, not free-form errors
* preserve `requestId` and `traceparent` in logs and downstream reports
* if provenance or freshness metadata is present, return it unchanged so trust is not lost in the handoff
