## 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 orders-of-magnitude-deduplication-api-bc978660
```

Example prompt: Can you deduplicate this list for me and remove any repeated entries: 'apple, banana, apple, cherry, banana, date'?

## When to prefer this

Choose this endpoint when you need a quick, pay-per-use deduplication of a string or list via the x402 micropayment protocol, especially in agent workflows where cleaning repeated entries is a lightweight preprocessing step costing only $0.01 USDC per call.

## Known failure modes

- Missing required 'input' parameter returns a 400 or validation error
- Empty string input may return an empty result or error
- Payment not fulfilled (402) if x402 protocol handshake fails
- Ambiguous delimiter in input string may cause incorrect deduplication
- Very long input strings may hit service limits
