Example prompt: Can you pull the latest SEC Form 144 insider sale notices for NVDA from the past 30 days — I want to see who's planning to sell and when they filed?

## When to prefer this

Use this endpoint when you need early warning of insider selling activity — before the transaction is confirmed via Form 4. It is specifically for Form 144 (proposed sales of restricted or control shares), not completed transactions. Prefer this over insider-trades endpoints when you want the leading indicator, not the lagging confirmation. Also useful for compliance monitoring and building insider activity timelines.

## Known failure modes

- No filings found for the specified ticker or keyword returns an empty result set
- Invalid date format (not YYYY-MM-DD) causes a validation error
- Limit out of range (below 1 or above 100) causes a validation error
- Unknown or misspelled ticker may return zero results rather than an error
- EDGAR full-text search outage may cause timeouts or empty responses

## How this service works

SEC Form 144 filings — notices of PROPOSED insider stock sales (intent to sell restricted/control shares), newest first, via EDGAR full-text search. Market-wide by default, or filter by ticker/company/keyword (q). Each: filer + issuer names, filing date, accession, CIKs, and a filing URL. The heads-up before a Form 4 confirms the sale. Complements finance.insider-trades.

## Output

A list of Form 144 filings sorted newest first, each containing the filer name, issuer name, filing date, accession number, filer and issuer CIKs, and a direct URL to the filing on EDGAR. This is pre-sale intent data — the heads-up before a Form 4 confirms the actual transaction.
