# Number Crunch – Statistical Analysis Suite

> Number Crunch – Statistical Analysis Suite is a paid API for AI agents from agent402.tools, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-15).

Runs descriptive statistics, correlation analysis, and outlier detection on a comma-separated list of numbers in a single bundled call.

## Facts

- Endpoint: POST https://agent402.tools/api/skill/number-crunch

- Payment: x402

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 number-crunch-statistical-analysis-suite-dc14c0b3 -d '<json body>'
```

Example prompt: Can you run a full statistical analysis on these numbers — 10, 12, 15, 11, 50, 13, 14 — and tell me the descriptive stats, any correlations, and flag any outliers?

## When to prefer this

Use this endpoint when you need a comprehensive statistical analysis (descriptive stats + correlation + outlier detection) in a single call and payment, rather than calling three separate statistical tools. Ideal for quick data quality checks, exploratory data analysis, or when you want a bundled cost-efficient statistical overview of a numeric dataset.

## Known failure modes

- Non-numeric values in the comma-separated list cause a parse error
- Empty or missing 'values' field returns a validation error
- Malformed input (wrong delimiter, extra spaces) may produce unexpected results
- Too few data points may make correlation or outlier detection unreliable or return an error
- Network timeout if the dataset is extremely large

## How this service works

Bundled execution of the Number crunch workflow - Statistical analysis suite: descriptive statistics, correlation analysis, and outlier detection on a single dataset. One x402 payment runs 3 underlying tools (stats-summary, correlation, outliers); partial-success per step.

## Output

Returns descriptive statistics (mean, median, standard deviation, etc.), correlation analysis results, and identified outliers from the input dataset — all three analyses bundled in a single response for one payment.
