## 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-numeric-array-sort-3d9eeff9 -d '<json body>'
```

Example prompt: Can you sort this list of numbers for me: [42, 7, 3, 99, 15, 1]?

## When to prefer this

Choose this endpoint when an AI agent needs a simple, trustless, pay-per-call numeric sort with verifiable delivery and no signup overhead — ideal for agents operating autonomously with USDC micropayment rails (x402 on Base or Solana) that need a deterministic utility function without standing up their own sort logic.

## Known failure modes

- Non-numeric values in the array may cause a validation error or unexpected results
- Empty array input may return a count of 0 and an empty items list
- Malformed JSON body returns an error response
- Payment failure via x402 results in a 402 Payment Required response

## 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 sorted numeric array under the 'items' key, a 'count' of elements, and a schema identifier ('delx/util-arr-sort-num/v1'). Payment is $0.001 USDC per call via x402 on Base or Solana.
