RealCite — SEC Filing Verification
Verify an SEC filing: given a filer's CIK and a claimed accession number, does that filing actually exist, and does its form type/filing date match what's claimed? Checked against SEC EDGAR's submissions API. Catches a fabricated or misattributed filing citation, including a real-looking accession number paired with an invented form type or date.
