## 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-73022cc3 -d '<json body>'
```

Example prompt: Can you compare these two versions of my paragraph and show me exactly what changed — what was added, removed, or modified between them?

## When to prefer this

Use this endpoint when you need a programmatic, pay-per-call text diff without setting up API keys or managing authentication. Ideal for AI agents that need to compare text on demand within automated workflows using USDC micropayments on Base.

## Known failure modes

- Missing or empty input text — returns error if one or both text inputs are not provided
- Input too large — very long texts may exceed processing limits or timeout
- Malformed request body — returns 400 if required fields are absent
- Payment failure — x402 payment not processed correctly results in 402 response
