## 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 text-diff-compare-b9d09dd8
```

Example prompt: Can you compare these two paragraphs and show me exactly what changed — I want to see what was added, removed, or modified between them?

## When to prefer this

Choose this endpoint when you need a quick, pay-per-call, no-signup text diff without integrating a full version control system or text processing library. Ideal for AI agents that need to programmatically compare two strings on the fly using USDC micropayments over x402.

## Known failure modes

- Missing or malformed schema parameter returns an error or empty diff
- Very large text inputs may exceed payload limits
- Identical inputs return an empty or no-change diff
- Malformed JSON in the schema field may cause a parse error
- Network timeout if the worker is cold-starting

## How this service works

309 deterministic pay-per-call tools for AI agents over x402 (USDC, Base). No signup, no API key: the payment is the identity.

## Output

A JSON response containing a structured diff of the two input texts, indicating which lines or segments were added, removed, or unchanged, returned as a deterministic comparison result.
