How this service works
Change watch for phone number extract: 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 phone number extraction from a page changes. $0.01 per check.
Output
Returns the current extracted phone numbers from the target page, a boolean 'changed' field indicating whether results differ from the previous call, a detailed list of exactly which fields changed with their before and after values, and a timestamp of when the data was last observed. Previous results are retained for 90 days.
Example use cases
Competitor contact page monitoring
“Watch the contact page at acmecorp.com/contact and tell me whenever the phone numbers listed there change — show me what numbers were there before and what replaced them.”
Client directory accuracy check
“Set up a recurring check on myclientsite.com/about so I'm notified if the phone number on that page ever gets updated or removed, with the exact before-and-after values.”
Franchise location phone tracking
“Monitor the location page at chainrestaurant.com/locations/downtown and alert me any time a phone number appears, disappears, or changes, so I can keep our records up to date.”
Technical details
Endpoint
GEThttps://intel.rallylive.ca/watch/site/phone-numbersWhen to prefer
Choose this endpoint when you need ongoing, scheduled monitoring of phone numbers on a specific webpage and want a built-in diff mechanism that tells you exactly what changed and when — rather than running a one-shot extraction and manually comparing results yourself. It is ideal for automated pipelines or agents that need to react to contact information changes without storing and comparing state on their own side.
Side effects
- Target URL is unreachable or returns a non-200 status, resulting in an error response
- No previous call exists for the URL so no diff is available on first call
- Phone numbers are rendered via JavaScript and not present in raw HTML, causing missed extraction
- Page behind authentication or firewall blocks the crawl
- URL has not been checked before within the 90-day window, so 'changed' may be indeterminate
