{
  "keyword": "Berkshire Hathaway",
  "daysBack": 45,
  "maxResults": 50
}

Field	Type	Description
`keyword`	string (optional)	Free-text search across the filing. Matches both the manager's own name and any company named in their reported holdings — searching `"Apple"` surfaces managers who hold Apple stock, not just companies named Apple. Leave blank for all new 13F filings market-wide.
`daysBack`	number	How many days back from today to search, by filing date. Default `45`, max `120`. 13F filings cluster around the 45-day-after-quarter-end deadline, so a wider window catches more filers.
`maxResults`	number	Max filings to return, most recently filed first. Default `50`, max `100`.

Output

One record per filing:

{
  "accessionNumber": "0002150492-26-000004",
  "filerName": "BERKSHIRE HATHAWAY INC",
  "filerCik": "0001067983",
  "filerTickers": "BRK-A, BRK-B",
  "filingDate": "2026-08-14",
  "periodOfReport": "2026-06-30",
  "filingUrl": "https://www.sec.gov/Archives/edgar/data/1067983/000215049226000004-index.htm"
}

A search with no matches in the requested window returns no items but is still billed once for the search.

How it works

Direct calls to the official SEC EDGAR full text search API (efts.sec.gov), filtered to Form 13F-HR filings. No proxy, no key, no scraping.

Note: 13F filings are two documents — a cover page (what this actor indexes) and a separate "information table" listing the actual security positions, share counts, and values. This actor tells you who just filed and when; use filingUrl to open the full filing for the line-by-line holdings.

Pricing note

Billed per search, not per filing returned — one charge whether the search returns 0 filings or 100.
