What it returns

The brief of etf-flows; prefer it unless you need every day. The same coin, market and limit: the net flow over every day of the window, in total and fund by fund, and the newest 30 days, each exactly as etf-flows lists it. A day or fund that had not reported adds nothing to a total; a total nothing reported to is null.

Chains

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