## 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-unique-sorted-array-utility-dbddf2e5 -d '<json body>'
```

Example prompt: Take this list [5, 3, 1, 3, 2, 5, 1] and remove all the duplicates, then sort what's left — tell me how many unique values there are too.

## When to prefer this

Choose this endpoint when you need a simple, pay-per-call utility to deduplicate and sort a list without setting up auth or subscriptions. Ideal for agents that encounter array deduplication as a one-off step in a pipeline and want verifiable, micropayment-priced execution on Base or Solana via x402.

## Known failure modes

- Missing or non-array 'items' field returns a validation error
- Empty array input may return count 0 with empty items array
- Non-comparable mixed types in array may cause sorting errors
- Payment failure via x402 prevents endpoint execution
- Network timeout on large arrays

## How this service works

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