Technical details
Endpoint
GEThttps://x402-sand.vercel.app/api/etf/funds?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need institutional-grade ETF flow and fund data specifically for crypto assets alongside US macroeconomic context, especially for Bitcoin or other major crypto tickers. Prefer this over general market data APIs when the focus is on ETF-specific institutional positioning rather than spot price or on-chain metrics.
Side effects
- Missing required 'asset' query parameter returns an error
- Invalid or unsupported asset ticker returns empty data array
- Upstream data source unavailable returns success:false or empty data
- Payment not fulfilled results in 402 Payment Required response
