## 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 nexusapi-text-diff-b3ccd66e -d '<json body>'
```

Example prompt: Show me the differences between these two versions of my paragraph: original: 'The quick brown fox jumps over the lazy dog.' and revised: 'The fast brown fox leaps over the sleeping dog.' — highlight what changed.

## When to prefer this

Use this endpoint when you need a quick, paid-per-call text diff computation without managing API keys, especially in agent workflows on Base where USDC micropayments via x402 are already in use.

## Known failure modes

- Missing or malformed input text returns an error
- Empty query string may produce no diff output
- Excessively large text inputs may time out or be rejected
- Payment failure in USDC results in 402 response blocking execution

## How this service works
