Technical details
Endpoint
GEThttps://api.myceliasignal.com/oracle/stress/equityWhen to prefer
Choose this endpoint when you need a single, authoritative composite equity stress signal combining multiple volatility and credit dimensions (VIX, VVIX, IV/RV, credit spread stress, DXY momentum) into one 0-100 score with cryptographic attestation. Prefer this over single-factor vol signals when you need a holistic, tamper-evident equity risk reading suitable for automated trading decisions, risk dashboards, or downstream agent workflows that require verifiable data provenance.
