GET

/events

1 cr

The cursor/diff workhorse. Poll with ?since=<seq> to get every filing event newer than your last cursor; the response's next_cursor advances it. The stream carries SEC Form 4 (insider) filings today; filter by form or tickers. Querying a form we don't ingest yet (8-K, 13D/G) returns an explicit unsupported_form note, never a silent empty page. Built for a watch loop.
