## 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 edgar-13f-hr-top-holdings-lookup-08efaf19
```

Example prompt: Show me the top 20 holdings from Berkshire Hathaway's most recent 13F SEC filing — you can use their ticker BRK-B or CIK 1067983.

## When to prefer this

Use this endpoint when you need structured, parsed 13F-HR portfolio holdings data for a specific institutional manager identified by SEC CIK or public ticker. Prefer this over scraping SEC EDGAR directly because it handles XML parsing, sorting, and normalization automatically. Best for research on large institutional investors (>$100M AUM) where quarterly snapshot data is sufficient.

## Known failure modes

- CIK not found or manager has never filed a 13F — returns error or empty result
- Ticker not resolvable to a CIK (many funds are not publicly traded) — use CIK directly instead
- Manager has less than $100M AUM and is not required to file 13F — no data available
- SEC EDGAR upstream unavailable — service may time out or return stale data
- Limit parameter out of range (must be 1-500) — returns validation error

## How this service works

Top holdings from an institutional investment manager's most recent 13F-HR filing (managers >$100M AUM file quarterly). Parses the standard SEC informationtable.xml attached to the filing - returns issuer, CUSIP, shares, USD value, and voting authority for each position. Sorted by USD value, descending. Source: data.sec.gov + filing archive. ?cik=1067983 (Berkshire) or ?ticker=BRK-B

## Output

A list of the manager's top portfolio positions sorted by USD value (descending), each including issuer name, CUSIP, number of shares, USD market value, and voting authority classification. Defaults to top 50 holdings; configurable up to 500.
