What is the Quantustik 8-K filings feed?

A paginated, dated feed of SEC 8-K material-event filings across the tracked S&P 500 universe, with each entry's event category (earnings, M&A, exec change, restatement, distress, financing, etc.) derived from the filing's own SEC Item number. Educational research; not investment advice.

How is this different from the 8-K digest on ticker pages?

The per-ticker digest is a rolling snapshot of one ticker's recent 8-Ks with no history. This feed reads the durable filing-events store across the whole tracked universe so you can page back through real dated history, optionally filtered by event type.

How often is the feed updated?

New 8-K filings are ingested on a scheduled cadence; the first page of results is refreshed frequently, older pages are stable history.
