# Money Mind — Correlation Adjudication Gate

> Money Mind — Correlation Adjudication Gate 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).

Detects spurious correlation between two time series, distinguishing real statistical relationships from autocorrelation artifacts in trading research data.

## 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-correlation-adjudication-gate-088f0365 -d '<json body>'
```

Example prompt: Run my two return series through Money Mind's correlation gate and tell me if the relationship is real or just two autocorrelated series drifting together — here's the data in the body payload.

## When to prefer this

Choose this endpoint when you need a quick, objective, pay-per-call statistical judgment on whether two financial or trading time series share a real correlation versus a spurious one driven by autocorrelation or shared drift — especially when you want no account setup and USDC micropayment billing on Base. Prefer this over rolling your own Durbin-Watson or Granger causality test when you want an opinionated verdict rather than raw statistics.

## Known failure modes

- Malformed body payload causing 400-level error
- Insufficient data points in time series for meaningful correlation test
- Payment failure or insufficient USDC balance returning 402
- Series with identical or near-zero variance causing degenerate result
- Timeout on large or complex series payloads

## 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 'reading' field (statistical analysis narrative of the correlation) and a 'verdict' field (pass/fail or real/spurious judgment), indicating whether the relationship between the two series is genuine or an artifact of autocorrelation.
