Endpoint
GEThttps://x402-sand.vercel.app/api/etf/flows?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need crypto-specific ETF flow data and institutional fund movements paired with US macroeconomic context. It is especially useful for financial agents that need to correlate institutional demand signals with macro events for assets like BTC or ETH, rather than relying on generic price feeds or on-chain data alone.
Side effects
- Missing required 'asset' query parameter returns an error
- Invalid asset symbol returns empty data array or error
- Unsupported time period format may return no results
- Service unavailable or payment failure returns non-200 status
- Empty data array returned if no ETF flow data exists for the requested period
