## 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 alphapulse-sec-edgar-13f-hedge-fund-holdings-checker-6741be6b
```

Example prompt: Pull the latest SEC EDGAR 13F filing for Pershing Square Capital Management — I want to see their top long US-equity positions verbatim, total book value, and how concentrated the portfolio is.

## When to prefer this

Use this endpoint when you need official, deterministic, verifiable US equity holdings data sourced directly from SEC EDGAR 13F filings for a named institutional investment manager. Prefer this over third-party data aggregators when regulatory accuracy and source fidelity matter, or when you need to cite an official filing. Best for allocator due diligence, compliance checks, and portfolio transparency research on US-listed long equity positions.

## Known failure modes

- Fund name not found in EDGAR — returns no matching filer error
- Fund has not filed a 13F (e.g. below $100M threshold) — returns filing not found
- EDGAR upstream unavailable — returns fetch/timeout error
- Ambiguous fund name matching multiple filers — may return wrong entity or disambiguation prompt
- Stale data if EDGAR updates are delayed

## How this service works

Hedge fund holdings check grounded in official SEC EDGAR 13F filings, fetched live: top long US-equity positions VERBATIM (issuer, value, shares), total book value, deterministic concentration figure, filing dates, and an honest read of what the book shape suggests — plus what 13F cannot tell you (performance, shorts, non-US). Name in, official filing out. For allocator and trading agents.

## Output

Returns verbatim top long US-equity positions (issuer name, market value, share count) from the fund's most recent 13F filing, plus total portfolio book value, a deterministic concentration figure, filing and period-of-report dates, and an explicit note on what 13F data cannot reveal (performance, short positions, non-US holdings).
