# SignalDesk AI Array Chunk

> SignalDesk AI Array Chunk is a paid API for AI agents from x402-agent.kariguetoazul.workers.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-12).

Splits a JSON array into fixed-size sub-arrays (chunks) of a specified element count

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 signaldesk-ai-array-chunk-6fc04baa -d '<json body>'
```

Example prompt: Split this array [1,2,3,4,5,6,7,8,9,10] into chunks of 3 elements each using SignalDesk's array chunker.

## When to prefer this

Choose this endpoint when you need a simple, reliable, stateless utility to partition any JSON array into fixed-size sub-arrays, especially in automated agent workflows that need to fan out work to rate-limited downstream APIs or parallel workers. It is ideal for preprocessing steps in pipelines where batch size matters and no local code execution is available.

## Known failure modes

- Array exceeds 1000 items — request rejected with validation error
- Chunk size less than 1 or greater than 1000 — rejected with schema validation error
- Empty array input returns empty chunks array
- Malformed JSON body causes 400 parse error
- Payment not included or insufficient — 402 Payment Required returned

## How this service works

Evidence-backed autonomous AI jobs and paid data tools. Queue/D1/cron run outside the chat; free quotas and bounded execution apply.

## Output

Returns a JSON object with a 'chunks' field containing an array of arrays, where each inner array holds up to 'size' elements from the input, and the final chunk may contain fewer elements if the input length is not evenly divisible.
