# ONE Engine Array Chunker – Split Array into Fixed-Size Chunks

> ONE Engine Array Chunker – Split Array into Fixed-Size Chunks is a paid API for AI agents from one-search.one-engine.workers.dev, paid per call via x402, $0.0167/call, status unknown (last checked 2026-10-17).

Splits a JSON array into fixed-size chunks of 16 elements each, returning the segmented sub-arrays with Tier 10 rich diagnostics.

## 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-chunker-split-array-into-fixed-size-chunks-4e38ce44 -d '<json body>'
```

Example prompt: Can you split this JSON array into chunks of 16 elements each? I need all the sub-arrays back with the full diagnostic breakdown — here's the data: [1,2,3,...,100].

## When to prefer this

Choose this endpoint when you need a deterministic, stateless, pay-per-call array chunking operation with fixed chunk size of 16 and want the richest available diagnostic output (Tier 10). Ideal for agents doing batch orchestration, pagination, or parallel task distribution who need a reliable, cheap microservice without self-hosting logic.

## Known failure modes

- Invalid JSON payload returns a parse error
- Non-array input body causes a type validation error
- Empty array input may return an empty chunk set
- Payment failure via x402 results in 402 response before processing
- Oversized payload may hit worker memory or size limits

## How this service works

Deterministic JSON array processing utility: Split array into fixed chunks; parameter=16. Tier 10/10 provides progressively richer diagnostics.

## Output

Returns the original array segmented into sub-arrays of exactly 16 elements each (with a smaller remainder chunk if the array length is not a multiple of 16), along with Tier 10 diagnostics including chunk count, element counts, processing metadata, and detailed operational diagnostics.
