What it returns

The daily net flow into (positive) or out of (negative) the US spot exchange-traded funds on a coin, in total and fund by fund, with the coin price that day. Oldest first, one entry per trading day, the newest limit days. A day on which no fund has reported yet has a null total, and a fund that had not reported has a null flow. market=hk answers the Hong Kong spot bitcoin funds instead (BTC only), which are small: most days no shares are created or redeemed and every flow is a real 0. Not scoped to any chain. A coin with no tracked funds in the market asked for answers 404.

Chains

This endpoint is not tied to a chain: it takes no chain in its request.
