## When to prefer this

Choose this endpoint when you need structured, machine-readable SEC Form 4 insider trading filings for a known public company identified by CIK, without signing up for an API key. Ideal for agents doing financial due diligence, monitoring insider activity, or enriching equity research workflows. Prefer this over direct EDGAR scraping when you want a clean JSON response and pay-per-call pricing with no subscription.

## Known failure modes

- Invalid or non-existent CIK returns empty results or error
- CIK with no Form 4 filings returns empty filings array
- Limit out of range (outside 1-20) may cause validation error
- SEC EDGAR temporarily unavailable causes upstream fetch failure
- Payment failure results in no charge and no response data

## How this service works

Recent SEC Form 4 insider filings (officers, directors, 10% owners reporting trades) for one company CIK, from EDGAR's public submissions index. Lists filings with dates and links; transaction amounts are not parsed.

## Output

Returns a JSON object with the company name, CIK, total count of filings returned, the source URL on SEC EDGAR, a timestamp of when it was checked, and an array of filing objects each containing the form type, filed date, accession number, document filename, and full URL to the filing on SEC.gov.
