## 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-array-sort-num-9b52e7fa -d '<json body>'
```

Example prompt: Can you sort these numbers for me: [42, 7, 100, 3, 55, 18]? I need them in numerical order.

## When to prefer this

Use this endpoint when your agent holds a list of numbers that need to be sorted and you want a stateless, no-retention, local computation with a predictable $0.001 USDC cost. Prefer this over rolling your own sort logic when you need a reliable, consistent API-based sort without storing data externally. Best for scores, prices, weights, or any numeric array that needs ordering.

## Known failure modes

- Non-numeric values in the items array may cause an error or unexpected sorting behavior
- Empty array input may return an empty result or error
- Malformed JSON body returns a 400-level error
- Missing items field in the request body returns a validation error

## How this service works

Sort a list numerically. Call when you order agent-held scores or prices. Returns sorted numbers and count for $0.001 USDC via x402 on Base. No network, no keys, no retention; first-party local JSON only. Results are advisory; the caller owns budgets, auth, and production controls.

## Output

Returns the input numbers sorted in ascending numerical order and a count of how many items were in the list.
