Technical details
Endpoint
POSThttps://minty-sprout.onrender.com/v1/fear-greed?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, standardized crypto market sentiment signal based on the widely recognized Fear & Greed Index. It is ideal for pre-trade analysis, daily briefings, or monitoring sentiment trends without building a custom data pipeline. Prefer this over raw on-chain metrics endpoints when a human-interpretable sentiment label (Fear/Greed) is sufficient.
Side effects
- Upstream alternative.me API unavailable — index data may be stale or missing
- Malformed or empty response if the data provider is experiencing downtime
- No historical data returned if fewer than 7 days of records are available from the upstream source
