# Numora ANOVA Statistics Endpoint

> Numora ANOVA Statistics Endpoint is a paid API for AI agents from numorapoi.orbonomy.xyz, paid per call via x402, $0.03/call, status unknown (last checked 2026-09-14).

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

## Facts

- Endpoint: POST https://numorapoi.orbonomy.xyz/api/statistics/anova
- Price: $0.03/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-14371176
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_cmCAMlAMwfnkNu5Wj2R8u

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-14371176 -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: [23, 25, 28, 22, 26], Group B: [30, 32, 35, 31, 33], Group C: [18, 20, 19, 21, 17].

## When to prefer this

Use this endpoint when you need pure server-side ANOVA computation without setting up a statistics library locally. Ideal for AI agents that need to compare three or more sample groups for statistical significance in research, A/B/C testing, or experimental analysis. Prefer this over general-purpose code-execution endpoints when you want a lightweight, deterministic math call with x402 micropayment billing at $0.10 per call.

## Known failure modes

- Missing or empty groups array returns a validation error
- Fewer than two groups provided causes ANOVA to be undefined — likely returns an error
- Groups with zero variance may cause division-by-zero edge cases
- Non-numeric values in group arrays may cause computation failure
- Payment not provided or insufficient USDC balance results in 402 response before computation

## 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 a boolean success flag, a result object containing ANOVA statistics (F-statistic, p-value, group means, variances, degrees of freedom, sum of squares), and a human-readable computation string describing what was calculated.
