Api Endpoint

etf-flows

Daily net creation/redemption flow for spot Bitcoin or Ethereum ETFs, computed from each issuer's own holdings disclosure: per-fund and total net flow in USD and coin for the latest day, a recent series and the window cumulative. One normalized call instead of polling each issuer site and differencing units.
