Endpoint
GEThttps://manylives.me/paid/crypto/fear-greed?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a simple, numeric sentiment gauge for the overall crypto market — especially for daily check-ins, trend monitoring over weeks, or triggering alerts at sentiment extremes. Prefer this over raw price feeds when what matters is market psychology rather than exact prices.
