Cross-asset ETF rollup — BTC + ETH + combined in a single call.

Dashboard-friendly single-call summary. Returns the latest day's flow, rolling 7-day flow, cumulative AUM, and all-time extremes for both BTC and ETH, plus the combined totals. Windows are fixed here — custom time ranges belong on the per-asset routes.

Query parameters

This endpoint takes no query parameters.

Response shape

Always wrapped in the standard envelope. Nullable fields are explicitly marked — treat missing numeric data as a real data-source gap, not as an error.

Notes

  • Combined totals are naive sums of BTC and ETH $M — the two assets have different price scales, so interpret accordingly.
