## When to prefer this

Use this endpoint when you need a high-level, aggregated view of the entire cryptocurrency market rather than data for a specific coin. Prefer this over the single-coin endpoints when you want macro indicators like total market cap, dominance ratios, or overall market sentiment. Ideal for dashboards, daily briefings, or pre-trade market condition checks.
