# ONE Engine Array Sort

> ONE Engine Array Sort is a paid API for AI agents from one-search.one-engine.workers.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-02).

Sorts an array of up to 1000 numbers or strings in ascending or descending order

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-sort-d8a8e21b -d '<json body>'
```

Example prompt: Sort these numbers in ascending order: [42, 7, 100, 3, 56]. Give me the full sorted list back.

## When to prefer this

Choose this endpoint when an autonomous agent needs a simple, stateless array sort as a utility step in a pipeline, especially when running in a serverless or lightweight context where importing a sort library is impractical or when the x402 micropayment model fits the cost structure. Ideal for agents that process heterogeneous data and need a reliable, low-cost sort primitive without spinning up compute infrastructure.

## Known failure modes

- Mixed types in array (numbers and strings together) cause a validation error
- Array exceeds 1000 items — request is rejected
- Invalid 'order' value (anything other than 'asc' or 'desc') causes an error
- Payment failure via x402 results in a 402 response and the sort is not performed
- Empty array may return an empty result or an error depending on implementation

## How this service works

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

## Output

A JSON object containing the sorted array under the 'values' key and a 'count' field indicating the number of items in the array.
