# Insider Trading Data API — SEC Form 4 Transactions

> Access structured insider trading data from SEC Forms 3, 4, and 5 via API. Track executive buys and sells, filter by transaction type, and detect patterns. Get started free at secapi.ai/signup.

Corporate insiders — officers, directors, and beneficial owners of more than 10% of a company's stock — must report their transactions to the SEC within two business days. SEC API parses Forms 3, 4, and 5 and exposes structured transaction data through a REST API.

## What you get

* **Transaction details**: Insider name, title, transaction type, shares, price, and value
* **Filtering**: By ticker, insider name, transaction type (purchase/sale), and date range
* **Historical data**: Form 4 transactions going back to 2004

## Quick start

Get recent insider transactions for a company:

```bash theme={null}
curl -H "x-api-key: $SECAPI_API_KEY" \
  "https://api.secapi.ai/v1/insiders?ticker=AAPL&limit=5"
```

```json theme={null}
{
  "data": [
    {
      "transaction_date": "2024-12-10",
      "insider_name": "Tim Cook",
      "insider_title": "Chief Executive Officer",
      "transaction_type": "sale",
      "shares": 200000,
      "price": 248.50,
      "value": 49700000,
      "shares_held_after": 3278651
    }
  ]
}
```

Filter for insider purchases only:

```bash theme={null}
curl -H "x-api-key: $SECAPI_API_KEY" \
  "https://api.secapi.ai/v1/insiders?ticker=JPM&transaction_type=purchase&limit=10"
```

## Use cases

### Insider buying signals

Insider purchases are widely studied as a bullish signal. Insiders sell for many reasons (diversification, taxes, liquidity), but they typically buy for only one: they think the stock is undervalued.

### Cluster buying detection

When multiple insiders at the same company or across a sector start buying simultaneously, it can indicate strong conviction. Scan groups of tickers for coordinated activity.

### Compliance monitoring

Track insider activity across your portfolio for regulatory compliance and conflict-of-interest checks.

### Executive compensation analysis

Combine insider transaction data with [compensation data](/seo/executive-compensation-api) to understand total executive ownership and trading behavior.
