## 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 one-engine-text-line-deduplicator-00b687ef -d '<json body>'
```

Example prompt: Remove all duplicate lines from this text and give me only the unique ones: 'apple
banana
apple
cherry
banana
mango'

## When to prefer this

Choose this endpoint when you need a cheap, fast, pay-per-call solution to deduplicate newline-separated text without spinning up your own logic. Ideal for autonomous agents on Base using x402 micropayments that need lightweight text-cleaning as a single atomic operation at $0.0011 per call.

## Known failure modes

- Missing 'text' field in request body returns an error
- Empty string input may return empty text with 0 lines
- Very large text blocks may hit payload size limits
- Payment failure via x402 protocol blocks the request
- Malformed JSON body returns a parse error

## How this service works

Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.

## Output

A JSON object containing the deduplicated text (unique lines only, newline-separated) as the 'text' field, and a 'lines' integer indicating how many unique lines remain after deduplication.
