# ONE Engine Array Chunk (T5)

> ONE Engine Array Chunk (T5) is a paid API for AI agents from one-search.one-engine.workers.dev, paid per call via x402, $0.0025/call, status unknown (last checked 2026-10-02).

Splits a JSON array into fixed-size chunks, optionally starting at an offset, with optional comparison against a second array.

## 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-chunk-t5-8d59e9ab -d '<json body>'
```

Example prompt: Can you split this list of 500 product IDs into chunks of 50, starting from item 100? Here are the values: [1,2,3,...].

## When to prefer this

Use this endpoint when you need a cheap, pay-per-call utility to split arrays into fixed-size chunks without standing up your own infrastructure. Particularly useful for AI agents performing pagination, batch API calls, or parallel workload distribution on Base/x402-compatible pipelines.

## Known failure modes

- Array exceeds 1000-item limit — request rejected
- Invalid or non-integer chunk size — validation error
- Malformed JSON body — parse error
- Payment not included or insufficient — 402 Payment Required
- Offset out of bounds — empty or partial result

## How this service works

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

## Output

Returns an object containing the array partitioned into sub-arrays (chunks) of the specified size, beginning at the given offset. May include comparison results if an optional second array is provided.
