## 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 x402-smartmoney-market-cfdb0fb1
```

Example prompt: Pull the quarter-over-quarter 13-F changes for Duquesne — I want to see all new buys, exits, increases, decreases, and any Form 4 updates from this quarter.

## When to prefer this

Use this endpoint when you need a fund-level view of portfolio changes between quarters — specifically what a single hedge fund bought, sold, increased, or decreased — including any intra-quarter Form 4 disclosures. Prefer this over the ticker-level fund positioning endpoint when your primary focus is the fund manager's activity rather than a specific stock.

## Known failure modes

- Fund slug not recognized or not tracked — returns error or empty result
- Fund has not yet filed its latest 13-F — data may be stale or unavailable
- Payment of $0.01 USDC not completed — 402 Payment Required response
- Invalid or missing slug parameter — schema validation error
- Rate limiting or service unavailability — 429 or 5xx response

## How this service works

Quarter-over-quarter 13-F changes for one tracked fund: new buys, exits, increases, decreases, position deltas, and fund-side Form 4 smart-money updates.

## Output

A structured breakdown of quarter-over-quarter 13-F portfolio changes for the specified fund, including new positions initiated, positions fully exited, increases and decreases in existing holdings, position size deltas, and intra-quarter Form 4 smart-money activity.
