How this service works
Spot Bitcoin ETF flows. Daily net flows, cumulative flow, AUM with per-fund breakdown (IBIT, FBTC, GBTC). Spot Bitcoin ETF flow data for research agents. A paid call serves today or any ?date= on record.
Output
A structured JSON or token-optimized markdown object containing Bitcoin ETF inflow/outflow metrics, a directional signal (bullish/bearish/neutral), a 7-day trend, a confidence score, and a generation timestamp. The 'context' field provides a plain-English summary ready for LLM consumption.
Example use cases
Daily BTC ETF flow check
“Get me today's Bitcoin ETF flows briefing — I want to know if institutions are buying or selling and what the overall signal looks like.”
Historical ETF flow analysis
“Pull the PreReason btc.etf-flows briefing for March 15, 2025 so I can compare how Bitcoin ETF demand looked around that date.”
Automated trading context pipeline
“Every morning, fetch the btc.etf-flows briefing in markdown format so my trading agent has the latest ETF flow context before it makes any decisions.”
Technical details
Endpoint
GEThttps://api.prereason.com/api/btc/etf?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need Bitcoin ETF-specific flow data combined with macro context in a single call, especially when feeding an AI agent that needs LLM-ready briefing text. Prefer over raw exchange APIs when you want pre-reasoned signals, confidence scores, and trend context without building your own aggregation layer. Best for automated financial agents that need daily or historical BTC ETF demand signals without post-processing.
