You shouldn't have to read the filing.

EDGAR ships HTML and cover-page XML built for lawyers. We do the parsing — item codes, the materiality call, the holder/target/percent extraction — so your code gets a field, not a document.

The activist-stake firehose

Every SC 13D and 13D-A, resolved to who is buying, what they're buying, and how much of the float they hold — pulled from the structured cover page, not a press release.

8-K item codes, in plain English

Item 2.02 becomes "Results of Operations", 5.02 becomes a leadership change, each with a material flag — so you filter the eight-figure events from the routine ones.
