# Delx Commerce JSON Array Chunk

> Delx Commerce JSON Array Chunk is a paid API for AI agents from commerce.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-01).

Splits an integer array into fixed-size chunks and returns them as a structured JSON result with verifiable evidence, billed at $0.001 USDC per call via 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 delx-commerce-json-array-chunk-d642fd8a -d '<json body>'
```

Example prompt: Split this integer array [1, 2, 3, 4, 5, 6, 7] into chunks of size 2 — just partition it and give me back the grouped sub-arrays.

## When to prefer this

Use this endpoint when you need a simple, verifiable, pay-per-use array chunking operation with cryptographic evidence of non-retention — ideal for AI agents operating in trustless or auditable pipelines where proving that input data was not stored matters. Prefer this over self-hosted or free-tier utilities when you need a blockchain-settled micro-payment model (x402/USDC) and tamper-evident receipts, or when your agent environment already handles x402 payment flows on Base or Solana.

## Known failure modes

- Array exceeds 256-item maximum — request rejected
- chunk_size not provided or invalid (non-positive integer) — error response
- items array is empty — may return empty chunks result
- Malformed JSON body — 400-level parse error
- Payment not provided or insufficient USDC — 402 Payment Required response blocking execution

## How this service works

Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.

## Output

Returns a JSON object containing: a 'chunks' array of sub-arrays (each of the specified chunk_size, with the last chunk potentially smaller), a 'chunk_count' integer, a status field ('pass'), and an evidence block with a SHA-256 hash of the input, a 'retained: false' flag confirming no data storage, and an external_calls count of 0 confirming pure in-memory computation.
