## 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 aayat-ai-sec-13f-fund-holdings-01d8ec83
```

Example prompt: What does Berkshire Hathaway currently own? Show me their top 20 positions from the latest 13F, including what changed since last quarter.

## When to prefer this

Use this endpoint when you need structured, parsed 13F data for any SEC-registered investment manager without scraping EDGAR directly. It is ideal for agents that need to quickly surface institutional holdings, compare quarter-over-quarter portfolio changes, or enrich investment research workflows. Prefer this over raw EDGAR lookups when you need clean JSON output with change deltas already computed.

## Known failure modes

- Manager name not found or ambiguous — returns an error or empty result; use the SEC CIK number for precision
- Manager has not filed a 13F (e.g., too small to be required to file) — no data returned
- 13F not yet published for the most recent quarter — data reflects the prior filing period
- Rate limit or payment failure — HTTP 402 if payment is not resolved
- limit parameter out of range (must be 1–100) — validation error

## How this service works

What does a fund own? An investment manager's latest SEC Form 13F portfolio: each US-listed position with shares, value and portfolio weight, plus what changed since the previous quarter (new, increased, decreased, sold out). Hedge funds, Berkshire Hathaway, banks, pension funds. Pass ?manager=Berkshire Hathaway (or a CIK) &limit=20.

## Output

Returns a structured list of up to the requested number of US-listed equity positions from the manager's latest SEC 13F filing, each including the stock ticker/name, number of shares held, market value, portfolio weight percentage, and (by default) a change flag indicating whether the position is new, increased, decreased, or sold out relative to the prior quarter. Summary totals across all reported positions are also included.
