Connects Claude to the FilingFirehose SEC EDGAR API for body-text-parsed filings. Exposes operations to fetch recent 8-K filings with buried-event detection (flagging when filer-reported items don't match body language), activist-tagged Schedule 13D/G filings searchable by investor name, and ATM offerings extracted from S-3 prospectus supplements. The free tier returns 72 hours of data; paid keys unlock historical search back to 2026. Reach for this when you need to catch unreported cyber incidents, officer departures, or material agreements that companies bury in generic 8.01 "other events" filings, or when tracking activist positions and shelf offerings programmatically.
