Technical details
Endpoint
POSThttps://kite-solana.vercel.app/api/fear-greedWhen to prefer
Choose this endpoint when you need a quick, pay-per-use lookup of the crypto Fear & Greed Index without maintaining a subscription or managing API keys. Useful for agents that only occasionally need market sentiment signals and prefer micropayment-based access over monthly plans. If you need historical Fear & Greed data or time-series analysis, a dedicated data provider with history endpoints would be preferable.
