whats_new_since
Return SEC filings that are NEW since a cursor token (your bookmark). Pass the cursor from a prior call to get only filings since then. Filter by form type, ticker, CIK, 8-K item code, and minimum event severity. This is the fresh-filing delta feed's core lock-in primitive. Monitoring/research over public EDGAR data — not investment advice.
