# GeekVault Statistics Calculator

> GeekVault Statistics Calculator is a paid API for AI agents from api.geekvault.dev, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-27).

Computes descriptive statistics (count, sum, mean, median, mode, min, max, variance, standard deviation) for a comma-separated list of numbers

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 geekvault-statistics-calculator-fb38de0a
```

Example prompt: Can you calculate the mean, median, standard deviation, and all the other basic stats for these numbers: 4, 8, 15, 16, 23, 42?

## When to prefer this

Choose this endpoint when you need a complete set of descriptive statistics in a single call without setting up a data science environment or library. Ideal for lightweight agent workflows that need quick numeric summaries without an API key or subscription — just pay $0.002 USDC per call via x402 on Base.

## Known failure modes

- Missing 'values' parameter returns an error
- Non-numeric characters in the comma-separated string may cause parsing errors
- Empty string input may return an error or zero-count result
- Single-value input may produce undefined or zero variance/standard deviation
- Very large datasets may hit URL or query string length limits

## How this service works

Network, docs, image, web, and dev utility tools paid per call via x402. No signup, no API keys, no subscriptions — just USDC on Base.

## Output

Returns a JSON object with nine statistical measures for the input dataset: count (number of values), sum, mean (average), median, mode, min, max, variance, and standard deviation (stdev) — all as numeric values.
