## 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 opentools-text-diff-588a0d35 -d '<json body>'
```

Example prompt: Can you diff these two paragraphs and show me exactly what changed — here's the original: 'The quick brown fox jumps over the lazy dog.' and the new version: 'The quick red fox leaped over the sleepy dog.'

## When to prefer this

Use this endpoint when you need a lightweight, free text diff computation without setting up a local diff library. It is well-suited for agents that need to programmatically compare two strings or documents and surface changes, especially in workflows involving document editing, version tracking, or review automation.

## Known failure modes

- Missing required input body — returns 400 if text fields are absent
- Malformed JSON body — returns 400 or 422 validation error
- Extremely large text inputs may time out or return an error
- Empty strings provided for both texts — may return empty diff or error
- Server unavailable on Cloudflare tunnel — returns 502 or 503
