## When to prefer this

Use this endpoint when you need real-time bid/ask spread data combined with fundamental valuation metrics like P/E ratio and market cap for a stock ticker — especially when you need more detail than a basic last-price quote. Prefer this over generic quote APIs when you need the full suite of Yahoo Finance enriched data in a single call.
