Technical details
Endpoint
GEThttps://x402-sand.vercel.app/api/etf/cefi?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a combined view of crypto ETF institutional flows and US macro event data in a single call, particularly for CeFi-focused market intelligence. Prefer this over general financial data APIs when your focus is specifically on crypto ETF inflows/outflows and their relationship to macroeconomic catalysts.
Side effects
- Empty data array returned if no ETF flow data is available for the requested period
- Payment required error (402) if USDC payment is not included
- API returns success:false if the upstream data provider is unavailable
- Stale or delayed data if macroeconomic event feeds are not refreshed in real time
