GEThttps://api.myceliasignal.com/oracle/breadth/equityWhen to prefer
Use this endpoint when you need a single, cryptographically attested composite score for overall equity market health, particularly breadth across sectors relative to their 20-day moving averages. Prefer this over raw price feeds when you want a normalized 0-100 signal suitable for risk-on/risk-off decision logic, or when you need a verifiable (Ed25519-signed) breadth measurement for downstream audit trails.
