How this service works
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.
Output
A normalized JSON payload containing per-fund net creation/redemption flows in both USD and coin amount for the requested asset and region, along with a recent time series of daily flows and a cumulative total for the window — all derived from issuer holdings disclosures without requiring the caller to poll individual ETF issuers.
Example use cases
Daily BTC ETF inflow monitoring
“Pull today's net flow data for all US spot Bitcoin ETFs — I want to see how much BTC and USD moved in or out across each issuer, and what the total net flow looks like.”
Ethereum ETF flow analysis
“What does today's ETH ETF flow picture look like for US spot Ethereum ETFs? Give me per-fund and total net flows in both USD and ETH, along with the recent trend series.”
Cumulative ETF flow tracking for the week
“I want to track cumulative net inflows and outflows for US Bitcoin ETFs over the recent window — pull the latest flow data so I can see whether the overall trend this week is net creation or redemption.”

Endpoint
GEThttps://api.agentstools.dev/etf/flowsWhen to prefer
Use this endpoint when you need a single normalized call to get Bitcoin or Ethereum spot ETF daily flow data aggregated from all major issuers, rather than scraping and differencing each issuer's individual holdings pages. It is the right choice for any workflow that needs per-fund and aggregate net creation/redemption flows in both USD and coin denomination, with a recent history series included — especially when building dashboards, alerts, or reports that track institutional crypto ETF demand.
