## 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 title-and-meta-description-change-detector-47c32ee9
```

Example prompt: Keep an eye on https://acme.com for me — let me know if the page title or meta description changes from what it was last time you checked, so I can catch any rebrand or SEO edits.

## When to prefer this

Choose this endpoint when you need lightweight, persistent monitoring of a specific page's title and meta description over time without running a full page scrape. It is ideal for catching rebrands, SEO edits, or site hijacks at minimal cost ($0.01/call) with 90-day history. Prefer it over general scraping endpoints when only title/description change detection is needed.

## Known failure modes

- URL is unreachable or returns a non-200 status — endpoint may return an error or empty diff
- Page has no title or meta description tags — returns empty strings with no change flagged
- First call for a URL has no previous state to compare — baseline recorded, no change reported
- Payment not accepted — x402 payment required error
- Rate limiting or network timeout reaching the target page

## How this service works

Title and description change detection: records a page's title and meta description on each call and tells you when either changes compared with your previous call (kept 90 days). Catch rebrands, hijacks and SEO edits. $0.01 per check.

## Output

Returns the current page title and meta description alongside the previously recorded values, a boolean indicating whether each changed, and the timestamp of the last recorded state. History is retained for 90 days.
