## 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 scriptmasterlabs-text-diff-api-281453d5
```

Example prompt: Compare these two paragraphs and show me exactly what changed — here's the original: 'The quick brown fox jumps over the lazy dog.' and here's the updated version: 'The quick red fox leapt over the sleeping dog.'

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call text diff computation without standing up your own infrastructure, especially when operating in a crypto-native or x402-payment-enabled agent pipeline and only occasional comparisons are needed at $0.001 per call.

## Known failure modes

- Missing or empty text input fields returns an empty or error response
- Malformed input schema causes a 400-level error
- Payment not settled in USDC via x402 results in a 402 Payment Required response
- Very large text inputs may result in timeout or truncated diff
- Ambiguous 'properties' parameter may yield unexpected results if not properly formatted

## How this service works

Pay-per-call crypto, RWA, federal, SEC, and compliance APIs. Settled in USDC on Base via x402. Hyphen routes only (e.g. /x402/rwa-aggregates, /x402/gas-tracker).

## Output

Returns a structured diff indicating which portions of the input text were added, removed, or unchanged, enabling the agent to identify exact changes between two text versions.
