# Numora T-Test Statistical Computation

> Numora T-Test Statistical Computation 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 a two-sample t-test on two numeric arrays, returning the t-statistic, p-value, and related statistical results

## Facts

- Endpoint: POST https://numorapoi.orbonomy.xyz/api/statistics/ttest
- 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-t-test-statistical-computation-cb1b4031
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_Z8wC2F9nOVelLH3CCZIoi

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-t-test-statistical-computation-cb1b4031 -d '<json body>'
```

Example prompt: Run a two-sample t-test on these two groups and tell me if the difference is statistically significant: group A is [23, 25, 28, 22, 27, 30] and group B is [19, 21, 18, 24, 20, 22].

## When to prefer this

Choose this endpoint when you need a pure serverless two-sample t-test with no external dependencies, especially in agentic pipelines that support x402 micropayments on Base. Ideal for lightweight statistical hypothesis testing without spinning up a full data science environment.

## Known failure modes

- Missing sample1 or sample2 arrays returns validation error
- Empty arrays may cause computation failure or undefined t-statistic
- Arrays with only one element may result in insufficient degrees of freedom
- Non-numeric values in arrays cause computation errors
- Payment failure via x402 micropayment returns 402 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 success=true, a result object containing t-statistic, p-value, and degrees of freedom, and a human-readable computation string describing what was calculated
