Endpoint
POSThttps://api.vextorium.com/fear-greed-pago?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a simple, real-time scalar sentiment indicator for the overall crypto market. Prefer this over custom sentiment analysis when you want the widely-recognized Alternative.me Fear & Greed Index specifically, or when you need a quick contrarian signal for crypto trading decisions without building your own data pipeline.
Side effects
- Upstream Alternative.me data unavailable — index value may be null
- Network timeout connecting to data source
- Stale or delayed data if upstream provider hasn't updated
- Malformed request body causing 400 error
