SEC Financial Reports API
SEC data API with 24h refresh, but Edgar, yfinance, and Alpha Vantage already solve this.

Yet another financial dashboard when Koyfin and Yahoo Finance already exist.
Retail investors, individual traders

Institutional holdings scraper; FactSet and Bloomberg terminals already own this.
Data-first move I appreciate: EDGAR-sourced, normalized financials plus 13F aggregation and a 'cluster buying' insider flag give immediate, actionable entry points for dividend and value investors. The UI is tidy and scannable — lists, recent updates and investor portfolios are surfaced clearly — but there’s nothing radically new here (no backtesting, unclear export/API options), so it’s a very useful tool for DIY research rather than a replacement for paid terminals.
Bloomberg-style UX for retail investors, but data sourcing and differentiation still unclear.
XBRL parsing is hell; this API serves raw SEC data without adjusted metrics.
PowerBI-lite for tech comps, but Crunchbase and PitchBook do this better with more data.
