## When to prefer this

Use this endpoint when you need the most current top-level crypto news headlines without needing to filter by specific coin or topic. It is ideal for quick market awareness, morning briefings, or monitoring breaking news. Prefer this over a coin-specific news endpoint when you want broad market-wide news rather than asset-specific coverage.
