## When to prefer this

Use this endpoint when you need a quick, real-time read of aggregate crypto market sentiment without building your own sentiment pipeline. Prefer it over social media sentiment scrapers when you want a standardized numeric index rather than raw text analysis, and over on-chain analytics when you specifically want the widely-recognized Fear & Greed composite score rather than individual metrics like funding rates or open interest.
