# JSON Array Chunk

> JSON Array Chunk is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-15).

Splits a JSON array of integers into ordered, bounded sub-arrays (chunks) of a specified size, returning deterministic versioned results.

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 json-array-chunk-2f8fd6e6 -d '<json body>'
```

Example prompt: Can you split this list of integers [1,2,3,4,5,6,7,8,9,10] into chunks of 3 so I can hand each group to the next step in my pipeline?

## When to prefer this

Choose this endpoint when an agent needs a stateless, deterministic, versioned record of chunking a bounded integer array — particularly when downstream tools enforce strict contracts and you need reproducible, auditable results. Prefer it over ad-hoc in-memory splitting when the transformation output needs a versioned envelope for traceability or when the chunking logic must be consistent across distributed agent steps.

## Known failure modes

- Array exceeds 256-item maximum — request rejected with validation error
- chunk_size is zero or negative — returns validation error
- items array is empty — may return empty chunk set or validation finding
- Non-integer values in array — schema validation failure
- Missing required fields — 400-level error response

## How this service works

JSON Array Chunk: JSON Array Chunk chunks a JSON array into bounded ordered groups from bounded caller-supplied values without an external provider. Call JSON Array Chunk before an agent hands structured data or a batch plan to a downstream tool with a stricter contract. Returns the bounded transformation or validation finding with counts, normalized values, and a versioned result contract for JSON Array Chunk as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base. First-party, st…

## Output

Returns a versioned deterministic JSON object containing the chunked sub-arrays (ordered groups), element counts per chunk, total item count, normalized values, and a versioned result contract identifier confirming the transformation.
