## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability sec-edgar-13f-institutional-holdings-filing-lookup-e49555ae
```

Example prompt: Pull the latest 13F holdings filing from SEC EDGAR for Bridgewater Associates — I want to see their full position breakdown and total portfolio value for the most recent quarter.

## When to prefer this

Use this endpoint when you need structured 13F institutional holdings data directly from SEC EDGAR — including portfolio value, position-level breakdowns, and filing links — for a specific fund manager identified by CIK, accession number, or name. Prefer this over generic SEC EDGAR browsing when you want parsed, machine-readable output rather than raw HTML filings.

## Known failure modes

- CIK not found in SEC EDGAR — returns error if CIK is invalid or unregistered
- Manager name resolution fails — best-effort name match may not find the correct filer; fallback to supplying CIK directly
- Accession number invalid or mismatched with CIK — returns error if accession does not correspond to provided CIK
- Quarter not yet available — if the requested quarter has not been filed, returns no results
- Rate limiting or SEC EDGAR downtime — upstream availability issues may cause timeouts or errors

## How this service works

One Form 13F filing normalized: the cover page plus every consolidated position with issuer, CUSIP, ticker, shares, value in US dollars, percent of portfolio and voting authority. Give an accession with its CIK, or a CIK or name with a quarter. A cheap granular pull.

## Output

Returns the institutional investor's total portfolio value, a breakdown of all reported equity positions (security name, shares held, market value, etc.), the filing period/quarter, and direct links to the underlying SEC EDGAR filing documents.
