AXISTRUTH is Aequara's B2B quantitative math layer — productized into two distinct offerings: the AXISTRUTH Math API (usage-based) for institutional developers and quant researchers, and AUCTOR, the per-seat analyst research platform powered by the same math substrate. HRP, Kelly, 4-factor scoring, Monte Carlo — the same infrastructure that underlies NPX-100.
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.
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.
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).
/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.
RESTful + streaming API for quantitative calculations — factor scoring, portfolio analytics, risk modelling, statistical functions. For institutional developers, quant researchers, hedge funds, RIAs, and fintech builders.
AXISTRUTH math API under the hood with a professional research workflow UX. For buy-side and sell-side analyst teams who need both the calibrated math and the institutional workflow. Annual per-seat pricing.
Aequara's flagship index uses HRP, Kelly, factor-scoring, and Monte Carlo regime simulation as core mathematical infrastructure. The AXISTRUTH Math API productizes that infrastructure into a clean REST surface with Bearer auth, tenant isolation, and usage-based billing. AUCTOR wraps the same math in a professional research workflow for institutional analyst teams — the named authority behind the numbers.
The same firewall applies: AXISTRUTH does not give you predictions about specific securities. It gives you the calibrated mathematical machinery to derive your own.
AXISTRUTH composes downstream into every Aequara surface that needs portfolio math. Authenticated via Aequara Trustee credentials. Same anti-issuer-pay firewall, same Brier-tracked discipline, same methodology hash discipline applied at the API tier.
Every sub-brand inherits the same NEXUS substrate · the same anti-issuer-pay firewall · the same Brier-tracking discipline · the same methodology-hash custody. Pick the surface that matches your work.
