Endpoint
POSThttps://kite-solana.vercel.app/api/sentiment/fear-greed?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, single-call lookup of the aggregate crypto market sentiment index without building your own sentiment pipeline. Prefer this over manual data aggregation when you want a pre-computed Fear & Greed score for trading signals, briefings, or decision support at $0.17 per call.
Side effects
- Upstream data source unavailable — returns generic error in result object
- Payment failure in USDC on Base chain — request not processed
- Stale or cached data returned if upstream index provider has not updated
- Generic 500 error with minimal detail due to thin response schema
