## When to prefer this

Use this endpoint when you need to discover or query tokenized equities (stocks or ETFs) available on Robinhood Chain, especially for building on-chain equity strategies, checking on-chain liquidity before trading, or monitoring which tokenized assets are currently live. Prefer this over generic stock price APIs when you specifically need on-chain tokenized asset data rather than traditional market data.
