For investors who want to see clearly (currently free :-))
Know what moves a stock before it's old news.
algoum turns official company disclosures into clear, easy-to-read updates - no jargon, no spreadsheets, just the moments that actually matter.
See it in action
One request, one plain-language fact - straight from SEC EDGAR.
Illustrative example, not a live call. Try it yourself once you have a key.
Company insiders
See when a company's own executives and directors buy or sell their shares. When the people who know a business best put their own money on the line, it's worth paying attention.
Form 4 · 4/A · Form 5 · 5/A
Breaking company news
The moment a company has to report something major - a leadership change, a merger, a crisis - you find it here, in plain language, instead of buried in a filing.
Form 8-K · 8-K/A · NT 10-K · NT 10-Q
Where the big money goes
Follow what the largest investment funds are buying and holding, updated every quarter, so you can see where serious capital is headed.
Form 13F-HR · 13F-HR/A · 13F-NT
Built on official filings from SEC EDGAR, the SEC's public filing system - always sourced, never guessed.
Built for algo trading, too
Behind the plain language sits a clean API. If you are an algorithmic trader, every Form 4, 8-K and 13F filing arrives as consistent JSON keyed by ticker, with the original SEC EDGAR filing linked on each record - ready for a backtest or a live strategy. As an algo trader you load the history once and then receive new events as a stream instead of polling EDGAR yourself.
New: MCP server
Ask your AI assistant about insider buys
Connect Claude, GitHub Copilot or Cursor to algoum and ask in plain language - the assistant looks up insider transactions, company events and fund holdings for you, from the same sourced data as the API. Nothing to install: an address and your API key.
