## 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 difficat-website-migration-comparison-80e1c090 -d '<json body>'
```

Example prompt: Run a migration comparison between my old site at https://old.example.com and the new one at https://new.example.com — check up to 50 pages for content and visual differences and generate a report with screenshots.

## When to prefer this

Use this endpoint when you need a comprehensive, automated comparison between a live source website and a migrated or redesigned copy — covering page existence, content diff, and visual regression in one job. Prefer it over manual QA or single-page screenshot tools when you need to validate dozens to thousands of pages systematically before a go-live event.

## Known failure modes

- Source or destination URL unreachable — job fails with connectivity error
- Pages list too large exceeding budget ceiling — job may be capped or rejected
- Site blocks crawlers/bots — pages may show as missing or fail screenshot capture
- maxPages limit reached before full discovery — partial report returned
- Invalid URL format — job creation returns validation error
- Insufficient payment — job not started due to x402 payment failure

## How this service works

Starts a website migration comparison: checks page existence, content and visual regression between a source site and its migrated copy, then produces a report with screenshots. Use it to verify a migration or redesign before go-live. Priced on the pages it compares (the urls list, or the pages discovery finds, at most the optional maxPages ceiling), no page limit: 0.02 USD per page for the first 1000, 0.01 USD beyond, charged upfront.

## Output

A migration comparison job report including per-page existence status (found/missing), content differences, visual regression screenshots, and an overall summary — accessible as a report once the job completes.
