# x402-toolbox Descriptive Statistics

> x402-toolbox Descriptive Statistics is a paid API for AI agents from x402-toolbox.shablony-pro.workers.dev, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-02).

Computes descriptive statistics (mean, median, variance, etc.) for a given dataset via a pay-per-call x402 API requiring no signup or API key.

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 x402-toolbox-descriptive-statistics-2e528161
```

Example prompt: Calculate descriptive statistics for this dataset: [4, 7, 13, 2, 9, 5, 11, 3, 8, 6] — I need the mean, median, variance, and standard deviation.

## When to prefer this

Choose this endpoint when you need quick, pay-per-call descriptive statistics computation with no API key or account setup required — ideal for AI agents operating autonomously with a USDC wallet on Base. Best when you want a deterministic, cheap ($0.001) stats computation without integrating a full data science library or managing credentials.

## Known failure modes

- Missing or malformed schema/dataset input returns an error
- Non-numeric data in dataset causes computation failure
- Payment failure via x402 prevents access to results
- Empty dataset returns error or undefined statistics
- Malformed JSON schema string causes parsing error

## How this service works

309 deterministic pay-per-call tools for AI agents over x402 (USDC, Base). No signup, no API key: the payment is the identity.

## Output

Returns a JSON object with computed descriptive statistics for the provided dataset, including measures of central tendency (mean, median, mode), dispersion (variance, standard deviation, range), and shape (skewness, kurtosis), along with confirmation fields ok:true and paid:true.
