Technical details
Endpoint
GEThttps://api.prereason.com/api/cross/breadth?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a broad, cross-asset view of market risk appetite and sector rotation — not Bitcoin-specific data. Prefer this over btc.* briefings when the question is about overall market participation, whether money is rotating between sectors, or whether risk appetite is expanding or contracting across asset classes. Ideal for macro context framing before diving into specific asset analysis.
