AXISTRUTH

by AEQUARA · productized portfolio mathematics

AXISTRUTH is the AI-powered portfolio-mathematics REST API that underwrites NPX-100 and the rest of the Aequara index family. HRP allocation with Ledoit-Wolf shrinkage. Fractional Kelly position sizing. Cross-sectional 4-factor scoring. Monte Carlo stress simulation against three calibrated regimes (GFC 2008, COVID 2020, Dotcom 2000). Math at API speed. Calibrated, not heuristic. Brier-tracked, not black-box.

— "What goes in: data. What comes out: verdict."

Four calibrated endpoints. One auth scheme. Stripe billing.

/v1/optimize-portfolio

HRP — Hierarchical Risk Parity allocation with Ledoit-Wolf covariance shrinkage. Lopez de Prado (2016) cluster-tree allocator avoids the known-bad-conditioning of Markowitz mean-variance, calibrated for sparse-history portfolios.

ii.

/v1/size-position

Fractional Kelly position sizer. Continuous and discrete modes. Calibrated to actual edge-estimate uncertainty (not the textbook full-Kelly that blows up at finite-sample edges). The sizer assumes you're wrong about your edge — and sizes accordingly.

iii.

/v1/factor-score

Cross-sectional 4-factor scorer: momentum, low-volatility, quality, value. Calibrated against rolling decile spreads, not textbook Fama-French. Returns scores with confidence bands and per-factor independence ratings (Diether-Malloy-Scherbina divergence flags).

Plus: stress-test, usage, billing.

/v1/stress-test — Monte Carlo simulator against GFC 2008, COVID 2020, Dotcom 2000 regimes. /v1/usage — current-month usage for the authenticated key. /v1/billing — Stripe Checkout sessions and webhook receiver.

Why AXISTRUTH exists

The math that underwrites NPX-100, productized for everyone else.

Aequara's flagship index uses HRP, Kelly, factor-scoring, and Monte Carlo regime simulation as core mathematical infrastructure. AXISTRUTH is the same code, productized into a clean REST surface with Bearer auth, tenant isolation, and Stripe billing. If you're building a portfolio tool, an allocator, a wealth dashboard, or a research notebook — AXISTRUTH gives you the calibrated math without the implementation burden.

The same firewall applies: AXISTRUTH does not give you predictions about specific securities. It gives you the calibrated mathematical machinery to derive your own.

"The instrument is bronze. The verdict is true. The math, productized."
