Why ALSN filings on EdgarKit beat the alternatives

Real-time, not batched. Yahoo Finance and most aggregators batch the SEC daily index. EdgarKit polls EDGAR every 30 seconds, so new ALSN filings appear here within a minute of SEC acceptance.
Developer-ready JSON. Whalewisdom and OpenInsider give you HTML tables you can read but not parse cleanly. Every transaction shown above is also available as structured JSON via the API.
Full transaction codes. Yahoo collapses Form 4 lines into 'Buy' / 'Sell'. We keep the raw transaction code (P, S, A, M, F, etc.) so you can filter compensation noise out of trading signal.
Footnote text preserved. Rule 10b5-1 plan references, indirect ownership disclosures, and gift transfers are all retained in the API response, not stripped.
Free tier covers it. 1,000 API calls/month, no credit card. Most ticker-specific workflows fit comfortably in free.
