## When to prefer this

Use this endpoint when you need a quick momentum snapshot of the Robinhood Chain market — specifically to find which pools or tokenized assets are experiencing the largest price swings in either direction over 24 hours. Prefer this over individual token quotes when you want a ranked, market-wide view rather than a single asset's price.
