Endpoint
GEThttps://payai.agentstools.dev/etf/briefWhen to prefer
Use this endpoint when you need a single-call comprehensive snapshot of spot crypto ETF flows, AUM, and a directional verdict without having to query multiple issuer endpoints and manually compute streaks, momentum, or concentration. Ideal for dashboards, trading signals, or research workflows that need a quick authoritative summary of BTC or ETH ETF market dynamics in the US or HK.
Side effects
- Invalid 'asset' value (not 'btc' or 'eth') returns validation error

- HK region is a scaffold and may return incomplete or placeholder data
- Upstream data source unavailable may cause stale or missing flow data
- Payment failure (x402) if USDC balance is insufficient
