# Money Mind A/B Test Adjudication

> Money Mind A/B Test Adjudication is a paid API for AI agents from money-mind-extract.onrender.com, paid per call via x402, $0.31/call, status unknown (last checked 2026-10-18).

Corrects A/B test results for multiple-comparison bias and determines whether variant B genuinely beat variant A in a statistically valid way.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability money-mind-a-b-test-adjudication-1fc9375e -d '<json body>'
```

Example prompt: I compared 12 variants in my trading strategy A/B test and variant B came out on top with a t-stat of 2.4 — can you run the multiple-comparison correction and tell me if that result is actually real or just the luckiest of 12 tries?

## When to prefer this

Choose this endpoint when you have an A/B test or experiment result and need to determine whether the winner is statistically valid after accounting for the number of variants compared (multiple-comparison correction). Especially useful when you suspect p-hacking, data dredging, or inflated t-statistics from testing many variants before reporting. Prefer this over a generic stats library when you want a pay-per-call, no-account-needed adjudication with a plain-language verdict.

## Known failure modes

- Missing required body fields causes validation error
- Insufficient data in the test body to compute correction
- Payment of 0.31 USDC not provided or rejected — 402 response
- Malformed HTTP input object returns schema error
- Ambiguous or incomplete variant count may produce unreliable correction

## How this service works

Pay-per-call adjudication for trading research.
Eleven gates that killed 35 of our own concepts. Is your backtest real, is your
price data real, is your t-stat inflated? USDC on Base, no account needed.

## Output

Returns a JSON object with a 'verdict' (pass/fail or real/not real judgment) and a 'reading' (detailed statistical explanation of whether variant B genuinely beat variant A after correcting for how many variants were compared).
