Endpoint
POSThttps://crypto.openverbs.com/v1/sentimentWhen to prefer
Choose this endpoint when you need a quick, structured sentiment signal for the overall crypto market — especially if you want a historical series alongside today's reading. It is ideal for dashboards, trading signals, or any workflow that needs a normalized 0–100 fear/greed score with a classification label rather than raw price data.
