Endpoint
GEThttps://agents.x402stock.xyz/api/v1/fear-greed/crypto?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, real-time sentiment pulse on the overall cryptocurrency market without constructing your own composite index. Ideal for agents making automated trading decisions, sentiment-gated workflows, or enriching financial reports with market mood context. Prefer this over raw price data endpoints when you need a human-readable sentiment classification rather than numeric price signals.
