## 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 creator-desk-unique-lines-utility-1f6fd7cd -d '<json body>'
```

Example prompt: Can you deduplicate this list of lines for me and return only the unique ones: 'apple
banana
apple
orange
banana
grape'?

## When to prefer this

Choose this endpoint when you need a quick, pay-per-use deduplication of line-separated text without setting up a local processing pipeline. It is well-suited for autonomous agents that need to clean text data on the fly within a workflow and are already using x402 micropayment infrastructure. Prefer alternatives (local scripts, pandas, etc.) for large-scale batch deduplication or when cost per call is a concern.

## Known failure modes

- Missing or empty 'value' field returns an error or empty result
- Malformed input (non-string, unexpected type) may return an error or unexpected output
- Payment failure via x402 protocol results in a 402 response before processing
- Service unavailability on Render free tier may cause cold-start latency or 503 errors

## How this service works
