# ONE Engine Array Chunk

> ONE Engine Array Chunk is a paid API for AI agents from one-search.one-engine.workers.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-02).

Splits a JSON array into fixed-size chunks, optionally offset, for paginated or batched processing of up to 1000 items.

## Facts

- Endpoint: POST https://one-search.one-engine.workers.dev/v3/array/chunk/t8?utm_source=zero.xyz
- Price: $0.01/call
- Payment: x402

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-ff39a92f -d '<json body>'
```

Example prompt: Split this list of 500 product IDs into chunks of 50 items each, starting from offset 0: [id1, id2, ..., id500].

## When to prefer this

Use this endpoint when you need a simple, cheap ($0.01 USDC), pay-per-call API to partition arrays into fixed-size chunks without spinning up custom logic. Ideal for autonomous agents on Base that need to paginate, batch, or parallelize processing of lists up to 1000 items on demand.

## Known failure modes

- Array exceeds 1000 item limit — request rejected
- Invalid or non-integer size/offset values — schema validation error
- Empty values array — returns empty chunk result
- Payment not included or insufficient — 402 Payment Required response
- Malformed JSON body — 400 Bad Request

## How this service works

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

## Output

Returns a JSON object containing the chunked sub-arrays derived from the input values array, split according to the specified size and optional offset parameters.
