Technical details
Endpoint
GEThttps://api.deepbluebase.xyz/sentiment/compositeWhen to prefer
Use this endpoint when you need a comprehensive, multi-signal crypto sentiment snapshot across the four major coins (BTC, ETH, SOL, XRP) in a single call. Prefer over single-metric endpoints when you need regime detection, RSI, momentum, and Fear & Greed combined. Best for trading agents, market briefing bots, or portfolio monitoring workflows that need a holistic market mood assessment at low cost ($0.01/call).
