How this service works
Fusion flow brief for spot Bitcoin or Ethereum ETFs in ONE call: latest total net flow, the inflow/outflow streak, the window cumulative, flow momentum, issuer concentration, total AUM and a deterministic accumulation, distribution or neutral verdict. Saves several issuer queries plus the differencing.
Output
A structured JSON object containing: latest total net flow (USD), the current inflow or outflow streak length, cumulative flow over the reporting window, flow momentum indicator, issuer concentration metric, total AUM across all issuers, and a deterministic categorical verdict of 'accumulation', 'distribution', or 'neutral' — all in a single response without requiring multiple issuer-level queries.
Example use cases
Bitcoin ETF accumulation check
“Is money flowing into or out of US spot Bitcoin ETFs right now? Give me the full brief including AUM, net flow, and whether it's an accumulation or distribution signal.”
Ethereum ETF momentum monitor
“Pull the ETF flow brief for spot Ethereum in the US — I want to see the inflow/outflow streak, momentum, and the verdict on whether ETH ETFs are being accumulated or distributed.”
Crypto ETF AUM and concentration snapshot
“What's the current total AUM and issuer concentration for spot Bitcoin ETFs in the US? Also tell me the net flow trend and give me the accumulation/distribution verdict.”
