Technical details
Endpoint
POSThttps://proxy.suverse.io/v1/data/suverse-fear-greed-indexWhen to prefer
Use this endpoint when you need a quick, structured crypto market sentiment signal — especially for contrarian trading logic (buy extreme fear, sell extreme greed), risk management triggers, or enriching financial dashboards with current and historical sentiment context. Prefer this over raw social sentiment or price-only data when you specifically need the standardized 0–100 fear/greed composite score.
Side effects
- Upstream data source unavailable — service returns error or stale data
- Payment failure — insufficient USDC balance or x402 payment not processed
- Rate limiting — too many requests in a short window
- Network timeout — proxy fails to reach the underlying index provider
