How this service works
Change watch for webpage link extractor: runs the check and compares it with the result from your previous call for the same url (kept 90 days), returning the current answer, changed true/false, exactly which fields changed with before/after values, and when it was last seen. Call it on a schedule to be told when extract all outbound links from a web page's main content as absolute urls, plus its headings outline and title changes. $0.01 per check.
Output
Returns the current extracted outbound links (as absolute URLs), headings outline, and page title, along with a boolean 'changed' flag, a detailed diff showing exactly which fields changed with before/after values, and a timestamp of when the data was last seen. Results from the previous call (kept for 90 days) are used as the baseline for comparison.
Example use cases
Competitor resource page link tracking
“Watch https://competitor.com/tools for me and alert me whenever they add or remove any outbound links — I want to know if they start pointing to new partners or resources.”
Partner site editorial change detection
“Monitor https://partner.com/blog/getting-started and tell me if the page title or heading structure changes — I need to know when they update that article.”
SEO internal link audit monitoring
“Set up a recurring check on https://mysite.com/sitemap-resources and notify me whenever any outbound links on that page are added, changed, or removed so I can keep my link audit up to date.”
Technical details
Endpoint
GEThttps://intel.rallylive.ca/watch/page-linksWhen to prefer
Choose this endpoint when you need to continuously monitor a specific webpage's outbound links, headings, or title over time and be notified of changes — rather than doing a one-off extraction. It is ideal for scheduled agent workflows, SEO change tracking, and competitive intelligence where knowing what changed (and exactly how) matters more than just knowing the current state.
Side effects
- URL is unreachable or returns a non-200 status — check may fail or return no content
- Page blocks crawlers (robots.txt or bot detection) — links may be incomplete or missing
- No prior call exists for the URL — first call returns current data with changed=false/null and no diff
- Page uses JavaScript rendering — statically inaccessible links may not be extracted
- 90-day retention window exceeded — previous result is gone and the next call resets the baseline
