Signal8 provides read-only SEC-filing intelligence and market data for US-listed companies, plus US congressional & executive-branch (STOCK Act) trading and FEC campaign-finance data. Typical workflow: - Resolve a company first with `search_companies` (name or ticker), then call company tools — `get_company_profile`, `get_quote`, `get_financials`, `get_short_interest`, `get_float`, `get_earnings`, insider trades (`get_insiders`), and institutional/total ownership (`get_institutions`, `get_ownership`). Most tools take a bare ticker (e.g. "AAPL"). - For SEC filing text/exhibits, use the EDGAR tools (`search_sec_filings`, `get_filing_document`). - For political trading use the politician tools (`get_politicians`, `get_politician_transactions`, `get_senate_trades_by_ticker`); for campaign finance use the donor tools. Prefer lightweight lookups (`get_company_profile`, `get_quote`) before the heavier `get_company_bundle`. Calls are metered by the caller's API-key tier, so batch intent into the most specific tool rather than many broad calls.
