How this service works
Institutional 13F holdings for one manager with quarter-over-quarter changes: new positions, full exits, increases and decreases, joined on CUSIP because issuer names change between quarters and are not a safe join key. Resolves managers by name as well as ticker, and reports a 13F-NT notice as a notice instead of an empty portfolio.
Output
A list of equity positions held by the specified institutional manager as of their most recent 13F filing, each labeled with a change status (new, added, reduced, exited, or unchanged) relative to the prior quarter. Positions are joined on CUSIP to handle issuer name changes across quarters. If the manager filed a 13F-NT (notice of no holdings), the response reports that notice rather than an empty portfolio. Results include share counts, and can be filtered to changed positions only.
Example use cases
Hedge fund portfolio change tracker
“Show me all the positions that changed in Bridgewater Associates' 13F this quarter compared to last — I want to see what's new, what they exited, and what they increased or decreased.”
Activist investor stake monitoring
“What does Pershing Square currently hold according to their latest 13F filing? Pull up to 200 positions and compare against the prior quarter so I can see what's new or exited.”
Index fund holdings audit
“Look up the 13F for Vanguard using their CIK 102909 and give me the last quarter only — I just need a snapshot of their current equity positions, no change comparison needed.”
Technical details
Endpoint
GEThttps://bryan-hermes.lenok-gorgon.ts.net:8443/v1/holdings?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need structured, parsed institutional 13F holdings with reliable quarter-over-quarter change labels. It is superior to raw EDGAR scraping because it joins on CUSIP (not issuer name) to correctly track renamed or restructured issuers, resolves managers by name or ticker in addition to CIK, and correctly handles 13F-NT notices. Prefer this over generic EDGAR full-text search when the goal is portfolio analysis rather than document discovery.
Side effects
- Manager name not recognized — no CIK match found for the provided name
- Manager has not filed any 13F — not a 13F filer or below AUM threshold
- 13F-NT filed instead of full portfolio — returns notice, not holdings
- Requested limit exceeds 500 — validation error
- Quarter comparison unavailable — only one quarter of data exists for a new filer
- CUSIP join failure for obscure securities — position may appear as new when it is not
- Payment not processed — x402 payment required before response is returned
