## 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 cravvol-web-compare-662dc7d1 -d '<json body>'
```

Example prompt: Can you compare the content of https://example.com/product-a and https://competitor.com/product-a and tell me what's different between them?

## When to prefer this

Use this endpoint when you need to programmatically compare the content of two specific web pages without setting up authentication or subscriptions — ideal for competitive analysis, A/B content checks, or detecting differences between two URLs. Pay-per-use USDC pricing via x402 makes it suitable for sporadic agent-driven comparisons.

## Known failure modes

- One or both URLs are unreachable or return non-200 status — success: false with error details
- Invalid or malformed URLs provided — validation error returned
- Payment not processed via x402 — 402 Payment Required response
- Target page is behind authentication or bot protection — empty or partial content returned
- Rate limiting by target servers — timeout or partial response
