Scored company briefs from SEC EDGAR for 14 large US companies (Apple, Microsoft, Nvidia, Amazon, Walmart, JPMorgan, Bank of America, Exxon, Pfizer, Lilly, J&J, UnitedHealth, Netflix, Disney): a fundamentals score built from XBRL revenue, income, cash flow, cash, debt, margins and liquidity, and a filing risk score from 8-K items, 13D filings and insider Form 4 activity. Every input carries its SEC citation. POST /v1/brief {vertical, entity_id} returns one scored brief; POST /v1/overview returns every brief at once; POST /v1/verticals lists them. Verticals: fundamentals (How healthy are this company's financials versus its own recent history?); filing-risk (Has this company filed anything risky lately?). Raw scored series: /v1/signals, /v1/signal, /v1/explain, /v1/catalog, /v1/events. Every response is a single JSON object. Research signal, not investment advice.
