# 8-K / 8-K/A material events for one CIK

`GET /api/v1/sec/edgar/8-k/{cik}/material-events`

8-K material events filed by the given CIK in the inclusive [from_date, to_date] window. The ``items`` CSV filter restricts to filings declaring at least one of the requested item codes (set intersection). Default per contract Section 6 is the high-signal subset ``1.01,2.01,5.02,8.01``. Pass ``items=all`` (or any value of ``all``/``*``) to disable the filter. Retention 730 days; out-of-window from_date returns 422.

## Path parameters

- `cik` string, required — Filer CIK.

## Query parameters

- `from_date` string, required — Inclusive window start (YYYY-MM-DD).
- `to_date` string, required — Inclusive window end (YYYY-MM-DD).
- `items` string, nullable — CSV of 8-K item codes to filter to. Default (omitted) = '1.01,2.01,5.02,8.01' high-signal subset per contract. Pass 'all' or '*' to disable the filter.
