zensei_index_about
What the Zensei Index is, how to read the score, how it is built, and what this server serves. Same wording as the website FAQ. Call it once before interpreting any score.
zensei_index_today
Today's Zensei Index for U.S. equities: the final score, its regime label, and the three layer scores (structural conditions, tactical filters, regime confirmations). The Zensei Index is a RISK score from 0 to 100: LOWER IS HEALTHIER. 0-20 Supportive, 20-40 Vulnerable, 40-70 Stressed, 70-100 Restrictive. A rising score means conditions are deteriorating, not improving. Call zensei_index_indicators to see why the score sits where it does.
zensei_index_indicators
The ten indicators behind today's Zensei Index, each with its current status, the layer it scores into, its weight in that layer, and the same explanation the website shows. Use it to explain why the index sits where it does. Indicator statuses run from healthiest to most stressed: Clear or Inactive (no stress), Watch (early warning), Stress (confirmed stress), Activated or Danger (full signal). Calibrating means not enough data yet; Unknown means no data.
