Full-text search across every aggregated data source in one call: news, SEC filings, court
Full-text search across every aggregated data source in one call: news, SEC filings, court opinions, academic papers, government records, and developer discussions. One query surfaces everything concordant across independently-sourced, citable results -- not a single-source wrapper. Optional source/category/since filters.
