How this service works
US Spot ETF Net Flows — The total net fund flow of the leading U.S.-listed spot Crypto ETFs, reflecting day-to-day changes in their holdings. Covers major Bitcoin ETFs (e.g. IBIT, GBTC, FBTC, ARKB, BITB) and Ethereum ETFs (e.g. ETHA, ETHE, FETH, ETHV, QETH) from issuers such as BlackRock, Grayscale, Fidelity, Bitwise, and VanEck. Data by Glassnode.
Output
A time series array of objects with Unix timestamps ('t') and net flow values ('v') representing the total net fund flow (inflows minus outflows) across major U.S. spot crypto ETFs for the requested asset, interval, and currency denomination.
Example use cases
Track institutional Bitcoin demand signals
“Pull the weekly net flows for Bitcoin ETFs across all major issuers — I need to see if institutions are accumulating or selling right now to gauge market sentiment.”
Monitor Ethereum ETF inflows for allocation
“Show me the daily net fund flows into Ethereum spot ETFs like ETHA and ETHE for the past month — I'm trying to understand if capital is rotating into Ethereum or staying in Bitcoin.”
Compare ETF issuer performance monthly
“Get the monthly net flows for Bitcoin and Ethereum ETFs broken down by issuer — specifically BlackRock IBIT, Grayscale GBTC, and Fidelity FBTC so I can see which funds are winning the institutional race.”
Technical details
Endpoint
GEThttps://x402.glassnode.com/v1/metrics/institutions/us_spot_etf_flows_netWhen to prefer
Use this endpoint when you need authoritative, Glassnode-sourced net flow data specifically for U.S.-listed spot crypto ETFs (Bitcoin and Ethereum), including fund-level coverage of IBIT, GBTC, FBTC, ARKB, ETHA, ETHE, and others. Prefer this over generic price or volume APIs when the question is about institutional fund flows rather than on-chain activity or spot market trading.

- Payment not included or insufficient USDC causes a 402 Payment Required response
