# ONE Engine Array Stats Pack T10

> ONE Engine Array Stats Pack T10 is a paid API for AI agents from one-search.one-engine.workers.dev, paid per call via x402, $0.015/call, status unknown (last checked 2026-10-02).

Computes a tier-10 statistical summary pack over an array of numeric values, returning tier-dependent statistical outputs.

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 one-engine-array-stats-pack-t10-299ed7bf -d '<json body>'
```

Example prompt: Can you run the tier-10 array stats pack on this list of numbers: [12, 45, 7, 89, 23, 56, 34, 78, 90, 11, 65]?

## When to prefer this

Choose this endpoint when you need a quick, low-cost pay-per-call statistical summary of a numeric array without spinning up a data science environment. Ideal for autonomous agents that periodically need descriptive stats on small-to-medium numeric lists as part of a larger workflow, especially when operating on Base with x402 micropayments.

## Known failure modes

- Empty or missing 'values' array returns an error or empty result
- Non-numeric values in the array may cause computation errors or be silently ignored
- Very large arrays may hit payload size or timeout limits on Cloudflare Workers
- Payment failure via x402 returns 402 status before computation begins
- Malformed JSON body returns 400 error

## How this service works

Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.

## Output

Returns a JSON object with 'tier' set to 10 and a 'result' field containing tier-dependent statistical outputs computed over the input array — likely including descriptive statistics such as mean, median, mode, variance, standard deviation, min, max, and percentile breakdowns.
