## 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 creator-desk-array-length-utility-0f76650f -d '<json body>'
```

Example prompt: How many elements are in this array: [10, 42, 7, 88, 3]? Use the array-length utility to count them.

## When to prefer this

Use this endpoint when you need a simple, programmatic, micropayment-gated utility to count array elements inside an autonomous agent pipeline, especially when you need a reliable JSON response with an explicit operation label confirming what was computed.

## Known failure modes

- Non-array input provided — may return an error or unexpected result if value is not an array
- Missing or malformed value field — request may fail or return null result
- Payment not completed — x402 micropayment required before processing; unpaid requests are rejected
- Server cold start on Render free tier — may experience initial latency or timeout

## How this service works

Machine-callable x402-paid utilities for autonomous agents.

## Output

A JSON response containing the computed array length as 'result' and the operation name 'array_length', confirming what was calculated.
