## 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 owlchart-insider-trading-activity-feed-58d0802b
```

Example prompt: Pull the last 5 days of insider trading activity for NVDA in the US market — show me both buys and sells so I can see if insiders are loading up or dumping shares.

## When to prefer this

Use this endpoint when you need aggregated insider trading signals with sell/buy ratios, biggest trade breakdowns, and multi-market coverage (US/EU/JP). Prefer this over general news APIs when you specifically need SEC Form 4 or equivalent insider transaction data with dollar-value aggregation. It is particularly useful for screening multiple stocks at once or monitoring market-wide insider sentiment rather than parsing individual filings.

## Known failure modes

- Invalid 'side' value not in enum returns error
- Days parameter outside 1-10 range may return error or be clamped
- Unknown ticker or name returns empty results rather than error
- Unsupported market code (not us/eu/jp) returns error
- Payment failure (x402) blocks data access
