# Delx Commerce — JSON Array Flatten One

> Delx Commerce — JSON Array Flatten One 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).

Flattens a JSON array by one level of nesting, returning the merged items with a count and verifiable audit evidence.

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-flatten-one-37af8e3a -d '<json body>'
```

Example prompt: Flatten this nested JSON array by one level: [[1,2],[3,4]] — I need a single flat list of all the items.

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-use, verifiable one-level array flatten with no signup and cryptographic proof of non-retention. Ideal for AI agents running automated pipelines that need auditability and deterministic pricing in USDC. Prefer over general-purpose code execution when you want a simple, bounded utility with an immutable audit trail rather than running custom code.

## Known failure modes

- Input array exceeds 256 items — request rejected
- Malformed JSON body — parse error returned
- Non-array value supplied for `items` field — validation error
- Network timeout on the payment layer before 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 the flattened array under `result.items`, the total item count under `result.count`, the operation schema label, a pass/fail status, and an evidence block including the SHA-256 hash of the input, a flag confirming no data was retained, and a count of zero external calls made.
