## 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 primeapi-text-diff-8a25e18d -d '<json body>'
```

Example prompt: Can you diff these two versions of my README file and show me what changed? Original: 'Hello world. This is version 1.' New: 'Hello world. This is version 2. New feature added.'

## When to prefer this

Use this endpoint when you need a fast, pay-per-call text diff computation without managing API keys. Prefer this over manual string comparison when you need structured diff output, or over local tooling when your agent environment lacks shell access to standard diff utilities.

## Known failure modes

- Missing or empty input text returns an error
- Malformed JSON in request body returns 400
- Texts that are identical may return an empty diff
- Very large text inputs may time out or be rejected
- Payment failure in USDC returns 402
