Technical details
Endpoint
GEThttps://x402-etf-macro-intelligence.vercel.app/api/etf/cefi?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need institutional-grade CeFi crypto ETF flow data, specifically inflows and outflows from centralized fund vehicles like spot Bitcoin or Ethereum ETFs. Prefer this over generic crypto price APIs when the goal is to gauge institutional sentiment or capital movement rather than spot prices. Best suited for macro analysis, trading signal generation, or market research workflows that depend on fund-level data.
