How this service works
Change watch for extract external links as json: runs the check, compares it with the result from your previous call for the same url (kept 90 days) and returns the current answer, changed true/false, the fields that changed with before/after values, and when it was last seen. Schedule it to be alerted when this changes. $0.02 per check.
Output
Returns the current list of external links found on the page, a boolean 'changed' flag indicating whether the result differs from the previous call for that URL, a diff showing which fields changed with before/after values, and a timestamp of when the page was last seen. Results are retained for 90 days for comparison purposes.
Example use cases
Competitor outbound link monitoring
“Watch my competitor's homepage at rivalsite.com and alert me whenever they add or remove external links — I want to see what changed compared to the last check.”
SEO link profile change detection
“Check myblog.com/resources for any changes to its external links since my last check and show me which links were added or dropped, plus whether anything changed at all.”
Compliance watch on partner page
“Monitor our partner's page at partner.example.com and tell me if any external links have changed since we last checked — I need before and after values so I can review what was modified.”
Technical details
Endpoint
GEThttps://page.intel.rallylive.ca/watch/page/external-links/json?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to detect changes in a web page's external link profile over time, rather than just extracting links once. It is ideal for scheduled monitoring workflows, competitive intelligence, SEO auditing, or compliance checks where you need to know what changed, not just what exists. Prefer this over a one-shot extraction endpoint when historical comparison and change alerting are required.
Side effects
- Target URL is unreachable or returns an error — check may fail or return stale data
- No previous result stored (first call) — 'changed' will be false or undefined, no diff available
- Page blocks crawlers — external links may be incomplete or empty
- Stored result expired (older than 90 days) — treated as first call, no diff
- Rate limiting or payment failure — call rejected with payment error
