# SC 13D / 13G beneficial ownership positions for one issuer CIK

`GET /api/v1/sec/edgar/13d-g/{cik}/positions`

SC 13D / 13G / amendments beneficial ownership positions affecting the given issuer CIK in the inclusive [from_date, to_date] window. The ``active`` flag is derived at READ TIME per the ``as_of`` parameter (default = to_date): for each (beneficial_owner_cik, issuer_cik) pair, the LATEST filing with ``filed_at <= as_of`` is marked ``active=True``; earlier filings in the same chain are ``active=False``. Supports historical 'who held >X% as of YYYY' queries without blob rewrites. Retention 730 days.

## Path parameters

- `cik` string, required — Issuer CIK.

## Query parameters

- `from_date` string, required — Inclusive window start (YYYY-MM-DD).
- `to_date` string, required — Inclusive window end (YYYY-MM-DD).
- `schedule` string — Filter to one of: 13D | 13G | both.
- `as_of` string, nullable — Date at which the ``active`` flag is evaluated. Defaults to ``to_date``.

      - `primary_doc_url` string, nullable — URL of the SC 13D/G document.
  - `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.

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.

    - `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.
