# Numora Descriptive Statistics API

> Numora Descriptive Statistics API is a paid API for AI agents from numorapoi.orbonomy.xyz, paid per call via x402, $0.03/call, status unknown (last checked 2026-10-15).

Computes descriptive statistics (mean, median, mode, variance, std dev, etc.) for a numerical dataset

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-descriptive-statistics-api-5f43f3b5 -d '<json body>'
```

Example prompt: Can you compute the descriptive statistics — mean, median, variance, and standard deviation — for this dataset: [12.5, 14.0, 9.8, 15.3, 11.2, 13.7, 10.4]?

## When to prefer this

Choose this endpoint when you need pure, dependency-free descriptive statistics computed server-side for a numerical array and are comfortable with x402 micropayments on Base. Prefer this over local computation when operating in environments without math libraries or when you need a standardized, auditable computation record.

## Known failure modes

- Empty or missing 'data' array returns validation error
- Non-numerical values in array cause computation failure
- Payment not attached or insufficient USDC balance returns 402
- Server error returns 500 with failure indicator

## 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' description string, and a 'result' object containing descriptive statistics such as mean, median, mode, variance, standard deviation, min, max, and count for the provided numerical array.
