## 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 diff-checker-api-klymax402-com-5719f834
```

Example prompt: Can you compare these two versions of my README and show me exactly what lines changed? Original: 'This is a simple tool.
It works well.' — Modified: 'This is a powerful tool.
It works very well.
Try it today.'

## When to prefer this

Use this endpoint when you need a quick, lightweight line-by-line text comparison without setting up a local diff tool — ideal for comparing document revisions, code snippets, configuration files, or any two strings where you want to programmatically identify what changed

## Known failure modes

- Missing text1 or text2 parameter returns an error
- Very large text inputs may cause timeouts or truncated results
- If both texts are identical, returns an empty or no-change diff
- Non-UTF-8 or binary content may produce garbled output

## How this service works

Compare two texts and show line-by-line differences

## Output

A line-by-line diff output showing which lines were added, removed, or unchanged between the two input texts
