Short, honest, copy-paste-ready. Everything here works today — if a page exists, the feature exists.
Quickstart
AlphaAssay is a statistical validation service for trading signals: you send a signal, it returns a structured verdict — pass, conditional…
Verdicts & the gradient
An AlphaAssay verdict is a diagnosis, not a yes/no oracle. Four outcomes exist: pass , conditional , fail and insufficient_evidence — and…
REST x402 gauntlet
AlphaAssay's x402 surface is exactly POST /x402/v1/gauntlet — a REST payment path, not a wrapper around every MCP tool. It needs no account…
Validate a signal
Validation is the core product: your signal goes through the full battery and comes back with a structured verdict. Three input shapes are…
Pre-register a call
Pre-registration records the hypothesis before its evaluation window. You deposit a canonical hypothesis; the service records its hash and…

Golden specimens
Golden specimens are known-answer test cases — the standing offer to catch us being wrong before you pay us. Each is a prepared signal with…
The calibration record
The calibration endpoint is a signed-or-explicitly-untrusted population and maturity disclosure. Calibration v0 is not an outcome score or…
Verify offline
Raw cryptography and platform trust answer different questions. Ordinary verdicts and the unsigned demo are not certificates. The public…
What we keep
This page is the complete retention inventory of AlphaAssay — everything the service keeps, per path, and everything it never keeps. It…
