What data it sees

Do you need an account

No: the server works without sign-in

Financial context your AI actually understands.

Your agent stops guessing. Numbers are AI's weakest input. PreReason delivers language, its strongest skill. One API call returns a pre-reasoned briefing with trend signals, confidence scores, regime classification, and causal narratives. Not raw data to parse. Context to act on.

17 briefings - BTC price, on-chain, mining economics, macro indicators (Fed, M2, yields, VIX, DXY) analyzed as BTC relationship signals

30 metrics - each with signal interpretation, 7d/30d/90d trends, percentile rankings, and momentum

6 agent prompts - daily briefing, risk check, mining profitability, regime classification, correlation scan, weekly recap

Markdown output (~60% fewer tokens) or structured JSON. Sub-second latency. Free tier with no credit card.
