## 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 insider-trades-cluster-buy-screen-752f63be
```

Example prompt: Show me all stocks where at least 3 distinct insiders made open-market purchases within the last 30 days — I'm looking for that classic cluster-buy bullish setup.

## When to prefer this

Use this endpoint when you need a precomputed, ready-to-consume screen specifically for the cluster-buy insider pattern — multiple distinct insiders buying open-market shares within a tight window. Prefer this over raw insider trade feeds when you want signal aggregation done for you, and over single-insider screens when the coordinated multi-insider bullish thesis is the focus.

## Known failure modes

- No issuers match the requested N/M threshold — returns empty result set
- Invalid or out-of-range parameters for N or M — returns 400-level error
- Stale data if underlying insider filing feed has a delay
- Payment not completed via x402 protocol — returns 402 Payment Required
- Rate limit exceeded — returns 429 Too Many Requests

## How this service works

Cluster-buy screen — issuers where >=N distinct insiders made open-market purchases within an M-day span; the classic bullish setup, precomputed

## Output

A list of issuers meeting the cluster-buy criteria, including ticker symbol, the number of distinct insiders who purchased, the date range of purchases, and other relevant transaction metadata — all precomputed for fast delivery.
