SEC 13F Institutional Holdings Tracker — by Filer

Pull SEC Form 13F-HR quarterly holdings for any institutional manager by CIK. One clean row per holding line — CUSIP, issuer name, share class, USD value, shares (or principal), put/call flag, investment discretion, sub-manager attribution, voting authority.

Built for cron (track "what did Berkshire just file?") and for ad-hoc research (pull 8 quarters of Bridgewater for a regime-change analysis). No auth, no scraping — pure SEC EDGAR.

Inputs

{
  "filerCiks": ["1067983", "1350694"],
  "lookbackQuarters": 1,
  "includeAmendments": false
}

input	default	notes
`filerCiks`	—	Required. List of EDGAR CIKs of the managers. Examples: `1067983` (Berkshire Hathaway), `1350694` (Bridgewater Associates), `1364742` (BlackRock), `1423053` (Citadel Advisors), `1697748` (ARK Investment Management).
`lookbackQuarters`	`1`	How many of the most recent 13F-HR filings per filer to pull. `1` = just the latest snapshot.
`includeAmendments`	`false`	If true, also pull 13F-HR/A (amendment) filings.
`userAgent`	(voiddo default)	SEC requires a User-Agent identifying the requester.

Output

One row per <infoTable> line in the 13F. A single holding may appear multiple times if multiple sub-managers (under the same filer umbrella) hold separate blocks — that's how SEC structures the filing and we preserve it (deduplicate downstream if you want a clean per-CUSIP roll-up).

Daily / weekly cron pattern

13F filings drop 45 days after each calendar quarter (so May 15, Aug 14, Nov 14, Feb 14). A weekly cron with lookbackQuarters: 1 catches each new filing within days of it being posted.

{ "filerCiks": ["1067983", "1350694", "1423053"], "lookbackQuarters": 1 }

Real-world questions this answers

Hedge-fund following. What did Berkshire just buy or sell vs. last quarter?
Smart-money flow. Which 13F filers piled into NVDA last quarter?
Risk monitoring. Track concentration in a single CUSIP across N filers.
Manager attribution. Berkshire's 13F includes ~15 sub-managers (Buffett, Combs, Weschler, …) — otherManagerNames tells you whose desk this position is on.

What it doesn't do

No 13F-NT (no holdings filings).
No 13D / 13G (those are a separate filing type for >5% beneficial ownership — different actor).
No put/call valuation analytics — raw filing data only.
No automatic delta-vs-prior-quarter computation — pull lookbackQuarters: 2 and diff downstream if you need that.
