How this service works

PreReason delivers market context for financial agents. Bitcoin on-chain metrics, macro indicators, and reasoning context in one API call.

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.”

When 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.
