We're building the most comprehensive crypto data API we can, and it's still growing — there's always a coin, a field or an endpoint we haven't got to yet.
Please tell us about any data you think Crypto Data API should nail but doesn't. We're data nerds who love to geek out about market data, trading bots, AI agents, or how to make your trading stack work in general. Prefer a form? Send feedback.

One row per settled US trade date, in USD millions. Each fund column is that fund's net creation (positive) or redemption (negative); the last column is the net total across every US spot ether ETF. Link to a day with #YYYY-MM-DD, e.g. #2024-07-31.
Settled figures only: a day appears once every fund has reported. Sources: Farside Investors (primary, with the per-fund breakdown) and SoSoValue (backup, net total only).
Each fund's net flow summed over the 7 trading days with a per-fund breakdown, largest inflow first.
GET /api/v1/market-intelligence/etf/eth/flows returns the newest days settled trade dates (up to 1000), oldest first: each row has trade_date, flow_usd (the net total across every fund) and its source. days=582 reaches back to 2024-07-23; keep the rows whose trade_date starts with 2024-07.
