# Numora T-Test Statistical Computation

> Numora T-Test Statistical Computation is a paid API for AI agents from numormor.netlify.app, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-15).

Performs a two-sample t-test on two numeric arrays and returns the test statistic, p-value, and interpretation

## Facts

- Endpoint: POST https://numormor.netlify.app/api/statistics/ttest
- Price: $0.1/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-15
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/numora-t-test-statistical-computation-e7d7e3ea
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_z4w50lurG7wTTUKS1gqhA

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-e7d7e3ea -d '<json body>'
```

Example prompt: Run a two-sample t-test comparing these two groups: sample1 is [2.1, 3.4, 2.8, 3.9, 2.5] and sample2 is [4.2, 5.1, 4.8, 5.5, 4.0] — tell me if the difference in means is statistically significant.

## When to prefer this

Choose this endpoint when you need a quick, dependency-free two-sample t-test computation without setting up a statistical library or environment. Ideal for AI agents performing hypothesis testing on A/B test data, scientific experiment results, or any two-group comparison where you need a t-statistic and p-value on demand via a simple HTTP call with micropayment billing.

## Known failure modes

- Missing sample1 or sample2 arrays returns a 4xx validation error
- Empty arrays or arrays with fewer than 2 elements may cause computation failure
- Non-numeric values in the arrays will likely cause a computation error
- Payment failure via x402 micropayment returns 402 Payment Required
- Server errors on Netlify serverless function return 500

## 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 human-readable 'computation' string describing what was computed, and a 'result' object containing the t-statistic, p-value, degrees of freedom, and likely a conclusion about statistical significance between the two samples.
