## 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-deduplicate-list-2dc539ef -d '<json body>'
```

Example prompt: Can you deduplicate this list for me: ['apple', 'banana', 'apple', 'cherry', 'banana', 'date'] and tell me how many duplicates were removed?

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call deduplication utility with no signup required and verifiable delivery via x402. Ideal for AI agent pipelines that need quick, cheap list sanitization without spinning up custom code or a full data-processing service. Best when the list contains strings or simple scalar values.

## Known failure modes

- Missing or empty 'items' array — likely returns an error or empty result
- Non-array input for 'items' field — schema validation failure
- Payment failure via x402 — 402 response requiring USDC payment on Base or Solana
- Network timeout for extremely large lists
- Unsupported item types (e.g. nested objects) may not deduplicate as expected

## How this service works

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