## When to prefer this

Choose this endpoint when you need a broad, real-time snapshot of up to 116 cryptocurrencies in a single call, including short and medium-term price change percentages and market metrics.

Ideal for dashboards, portfolio tracking, or any workflow needing current market conditions across a wide range of coins at low cost per call.
