Choose this endpoint when you need broad, general U.S. stock market and personal finance news headlines rather than a specific topic. Prefer this over the Fed policy or sector-specific sibling endpoints when the user wants a general market overview. Best suited for morning briefings, news digests, or market sentiment checks rather than targeted keyword filtering.
