# Numora ANOVA Statistics Endpoint

> Numora ANOVA Statistics Endpoint is a paid API for AI agents from numormo.vercel.app, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-14).

Performs one-way Analysis of Variance (ANOVA) across multiple data groups to test whether their means differ significantly

## Facts

- Endpoint: POST https://numormo.vercel.app/api/statistics/anova
- Price: $0.1/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/numora-anova-statistics-endpoint-4101ccdb
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_4s-PbNx0xgHe2Gf2wixW0

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 numora-anova-statistics-endpoint-4101ccdb -d '<json body>'
```

Example prompt: Can you run an ANOVA test on these three groups of measurements to see if their means are significantly different: Group A is [12.3, 14.1, 11.8, 13.5], Group B is [18.2, 17.9, 19.1, 18.5], and Group C is [10.2, 11.1, 9.8, 10.5]?

## When to prefer this

Choose this endpoint when you need a pure server-side, zero-dependency ANOVA computation without setting up a statistics library locally. It is ideal for AI agents that need on-demand statistical testing as part of automated analysis pipelines, when you have 2 or more groups of numeric data and want to know if their means differ significantly. Prefer this over general-purpose compute endpoints when you specifically need ANOVA with a clean JSON response and micropayment billing.

## Known failure modes

- Missing or empty 'groups' array returns validation error
- Fewer than two groups provided causes ANOVA to fail (requires at least 2 groups)
- Groups with fewer than 2 data points may produce degenerate results
- Non-numeric values in group arrays cause computation errors
- Payment failure via x402 micropayment returns 402 status

## How this service works

100 pure math computation endpoints for AI agents. Statistics, financial math, linear algebra, equation solving, calculus, number theory, sequence generation, and unit conversions. Zero external dependencies. x402 micropayments on Base.

## Output

Returns a JSON object with 'success' (true), a 'result' object containing ANOVA statistics such as F-statistic, p-value, degrees of freedom, sum of squares, and significance indicators, plus a 'computation' string that describes in plain English what was calculated.
