How this service works
13F holdings, fund holdings. The latest 13F-HR holdings of an institutional investment manager (hedge fund, mutual fund family, bank) from SEC EDGAR: each position's issuer, class, CUSIP, value in USD, shares and portfolio weight, largest first, plus the report period, total value and position count. Give the filer by name (e.g. Berkshire Hathaway) or CIK. Public SEC data, filed quarterly up to 45 days after the quarter. Use to see what a fund owns.
Output
Returns a JSON object with the filer's name, CIK, SEC filing URL, form type, filing date, report period, and an array of holdings sorted by USD value descending. Each holding includes the issuer name, share class, CUSIP, number of shares, market value in USD, portfolio weight as a percentage, and optionally whether the position is a put or call. Also includes total portfolio value and total position count.
Example use cases
Research a hedge fund's equity portfolio
“What does Bridgewater Associates currently own according to their latest 13F? Give me their top 30 positions with the value and weight of each.”
Track a fund manager's holdings by CIK
“Pull the latest 13F holdings for the institution with SEC CIK 1067983 and show me all positions sorted by largest first.”
Compare fund positions for investment analysis

Technical details
Endpoint
GEThttps://agent-data-tools.revmesh2074.workers.dev/sec/13f?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need structured, per-position institutional holdings data directly from SEC EDGAR 13F-HR filings. It is ideal when you know the fund manager's name or CIK and want the most recent quarterly snapshot of what equities they hold. Prefer this over web scraping or financial data aggregators when you need authoritative regulatory filings with CUSIP identifiers and exact share counts.
Side effects
- Fund name not found on EDGAR — try providing the CIK directly
- CIK does not correspond to a 13F filer — manager may not be required to file
- No 13F filed yet for the current quarter — data lags up to 45 days after quarter end
- Ambiguous fund name matching multiple filers — use CIK for precision
- limit parameter out of range (must be 1–200)
