How this service works
Website change detection, step two: re-fetch a page saved with monitor.snapshot and get whether it changed, how old the baseline is, and a written summary of what changed. Use it to track price changes, terms updates, new job posts or competitor moves. Input: url; optional language.
Output
Returns a boolean indicating whether the page changed since the last snapshot, plus a human-readable summary describing what specifically changed (e.g. text additions, removals, price differences, new elements).
Example use cases
Competitor pricing page monitoring
“Has https://competitor.com/pricing changed since I last checked it? If so, tell me what's different.”
News article edit detection
“Re-fetch https://news-site.com/article/breaking-story and let me know if the article content has been updated or edited since the snapshot.”
Product availability tracking
“Check https://store.com/product/widget-pro and tell me whether anything on the page has changed — especially stock status or price.”
Technical details
Endpoint
POSThttps://hubvibe-io.com/work/monitor/check?utm_source=zero.xyzWhen to prefer
Use this endpoint when you have already called the snapshot endpoint for a URL and want to detect whether that page has changed. Ideal for recurring monitoring tasks, price watching, content tracking, or detecting edits to web pages. Prefer this over general-purpose web fetchers when change detection and diff summarization are the primary goal.
Side effects
- URL is unreachable or returns non-200 status — endpoint may return an error or indicate the page could not be fetched
- No prior snapshot exists for the given URL — check will fail or return an error indicating snapshot must be taken first
- URL returns a dynamically rendered page that differs each load due to ads or timestamps — may produce false positives
- Rate limiting or bot-blocking by the target site — fetch may fail or return incomplete content
