# Numora Descriptive Statistics Computation

> Numora Descriptive Statistics 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).

Computes descriptive statistics (mean, median, mode, variance, standard deviation, etc.) for a given numerical dataset

## Facts

- Endpoint: POST https://numormor.netlify.app/api/statistics/descriptive
- 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-descriptive-statistics-computation-15c3429b
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_9hseH_Af-ufB00_LhGWHf

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-computation-15c3429b -d '<json body>'
```

Example prompt: Calculate the descriptive statistics — mean, median, mode, variance, and standard deviation — for this dataset: [12, 15, 14, 10, 18, 22, 14, 9, 17, 14, 21].

## When to prefer this

Use this endpoint when you need fast, pure-math descriptive statistics computed server-side without any external dependencies — ideal for AI agents that need a quick statistical summary of a numerical array without spinning up a local math library or Python runtime. Prefer over general-purpose code execution endpoints when you want deterministic, pay-per-use micro-computation via x402 micropayments.

## Known failure modes

- Missing 'data' field returns validation error
- Empty array may return error or degenerate statistics
- Non-numeric values in array cause computation failure
- Very large arrays may timeout
- x402 payment not provided or insufficient USDC causes 402 Payment Required response

## 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 success flag, a result object containing descriptive statistics (such as mean, median, mode, variance, standard deviation, min, max, range, and count) for the input dataset, and a human-readable computation description string explaining what was calculated.
