# ONE Engine Array Chunk (t1)

> ONE Engine Array Chunk (t1) is a paid API for AI agents from one-search.one-engine.workers.dev, paid per call via x402, $0.0005/call, status unknown (last checked 2026-10-02).

Splits a JSON array into fixed-size chunks, optionally offset and compared against another array.

## Facts

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-chunk-t1-582466ac -d '<json body>'
```

Example prompt: Split this list of 200 product IDs into chunks of 25 — here's the array: [1,2,3,...,200].

## When to prefer this

Use this endpoint when you need a lightweight, pay-per-call array chunking utility without spinning up your own infrastructure. Ideal for autonomous agents that occasionally need to partition arrays as part of a larger workflow, especially when operating on the Base blockchain with x402 micropayments. Prefer this over writing custom chunking logic when you want a stateless, serverless call with no setup cost.

## Known failure modes

- Array exceeds 1000-item limit — request rejected
- Missing required 'values' field — validation error
- Invalid size or offset type (non-integer) — schema error
- Payment failure via x402 — 402 response, call not processed
- Empty array input returns empty chunks

## How this service works

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

## Output

Returns an object containing the input array split into sub-arrays of the specified chunk size, starting at the given offset. If a comparison array is provided, the result may include comparative data between the chunked values and the other array.
