## 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 whale-memory-api-insider-trades-f3e5e728
```

Example prompt: Pull the latest insider buy and sell activity — I want to see which CEOs or founders are accumulating their own stock right now.

## When to prefer this

Use this endpoint when you need a quick, low-cost snapshot of recent insider buying and selling activity — especially CEO and founder accumulation — without having to scrape OpenInsider yourself. Prefer this over the combined whale digest endpoint when you only need insider data (not 13F filings), and over SEC EDGAR when you want pre-processed, human-readable trade summaries rather than raw filings.

## Known failure modes

- Payment not included or insufficient (402 Payment Required)
- OpenInsider data source temporarily unavailable (503)
- No recent insider trades found for current period (empty result set)
- Rate limiting if called too frequently (429)

## How this service works
