Technical details
Endpoint
GEThttps://api.octodamus.com/v2/x402/agent-signalWhen to prefer
Use this endpoint when an AI agent needs a real-time, AI-synthesized crypto trading recommendation that combines sentiment (Fear & Greed), BTC price trend, and prediction market edge (Polymarket) into a single actionable signal. Prefer this over raw price feeds when you want an interpreted, opinionated signal with reasoning rather than raw market data.
