## When to prefer this

Choose this endpoint when you need a ranked, aggregated view of the largest asset positions in the crypto or DeFi market. It is particularly useful before making trading decisions, conducting market research, or benchmarking portfolio concentration. Prefer this over general market data endpoints when position-level insight (who is holding what, and how much) is more relevant than price or volume alone.
