## 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 sec-form-4-insider-transactions-api-9a917bf7
```

Example prompt: Pull the SEC Form 4 insider transactions for NVDA over the last 60 days, only show purchases (code P), filter out anything below $10,000, and flag if multiple insiders are buying.

## When to prefer this

Choose this endpoint when you need fast, normalized SEC Form 4 insider transaction data for a specific issuer with pre-computed net buy/sell aggregation and cluster buy detection. It is ideal for investment research agents, stock screening workflows, and event-driven trading signals that require detecting coordinated insider activity. Prefer this over raw EDGAR scraping when you need structured, filterable data with minimal processing overhead.

## Known failure modes

- Missing or invalid ticker/CIK returns a 400 error
- Unknown ticker symbol not found in SEC database returns empty results or 404
- days parameter out of range (>365 or <1) returns a validation error
- Invalid SEC transaction codes in the codes parameter may return empty results
- Rate limiting or payment failure returns a 402 response requiring USDC payment
- No filings found in the window returns an empty transactions array with cluster_buy false

## How this service works

Normalized SEC Form 4 insider transactions for one issuer, with per-transaction buys/sells and a summary containing net buy/sell value plus a cluster_buy flag (true when 2+ distinct insiders bought within the window).

## Output

Returns a list of normalized SEC Form 4 insider transactions for the specified issuer, each including transaction type, code, date, insider name/role, share count, price, and USD value. Also includes aggregated net buy and sell values across all returned filings, and a cluster_buy boolean flag that is true when 2 or more distinct insiders have executed buy transactions within the lookback window.
