# ONE Engine Array Minimum

> ONE Engine Array Minimum is a paid API for AI agents from one-search.one-engine.workers.dev, paid per call via x402, $0.0009/call, status unknown (last checked 2026-10-02).

Returns the minimum value from an array 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 one-engine-array-minimum-2291ca16 -d '<json body>'
```

Example prompt: Find the minimum value from this list of numbers: [42, 7, 18, 3, 99, 55, 21].

## When to prefer this

Choose this endpoint when you need a simple, pay-per-call minimum computation without spinning up local compute or managing dependencies. Ideal for autonomous agents on Base that need lightweight numeric reduction over small-to-medium arrays (up to 1000 numbers) and want to pay only $0.0009 USDC per call via x402. Prefer native language built-ins if you're running code locally or need to process arrays larger than 1000 items.

## Known failure modes

- Empty array input — API likely returns a 4xx error since the array must be non-empty
- Array contains non-finite values (NaN, Infinity) — rejected per schema constraint
- Array exceeds 1000 items — returns a validation error
- Non-numeric values in the array — schema validation failure
- Insufficient USDC balance for x402 payment — payment rejected before computation

## How this service works

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

## Output

A JSON object with a single field 'value' containing the minimum number found in the input array, e.g. {"value": 2}.
