Every SEC filing by one issuer SINCE a cursor - a delta, not a dump. Requires ?since=YYYY-MM-DD AND ?ticker= or ?cik= (cik wins if both). Optional ?forms=10-K,8-K (also matches /A), ?limit=1..200. Errors: 400 missing_since|missing_issuer|bad_since|bad_ticker|bad_cik|bad_limit, 404 unknown_ticker|unknown_cik, 502 edgar_unavailable, 503 rate_limited_locally. AN EMPTY DELTA IS CHARGED: nothing-changed is the answer you bought. 8-K with decoded items: /edgar/events. Ownership: /edgar/insiders.
