How this service works
Change watch for extract paragraphs 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 a JSON object containing the current extracted paragraphs, a boolean 'changed' field indicating whether content differs from the previous check, a diff showing the specific fields that changed with before/after values, and a timestamp of when the content was last seen. History is retained for 90 days.
Example use cases
Competitor pricing page surveillance
“Watch https://competitor.com/pricing and let me know the moment the paragraph text changes — show me what changed before and after so I can see if they updated their pricing terms.”
News article update tracker
“Check https://bbc.com/news/article-12345 for paragraph changes and tell me if the story has been edited since last time, with a diff of what was added or removed.”
Policy page compliance monitoring
“Monitor https://vendor.com/terms-of-service for any paragraph changes — I need to know if the text has shifted since my last check so I can flag it for our legal team.”
Technical details
Endpoint
GEThttps://page.intel.rallylive.ca/watch/page/paragraphs/json?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to detect whether paragraph text on a specific web page has changed since your last check, and want structured before/after diff data. Prefer this over a plain extraction endpoint when change detection and alerting are the primary goal. Use the bulk variant when monitoring multiple URLs simultaneously.
Side effects
- Target URL is unreachable or returns non-200 status — extraction fails with an error
- No previous result stored (first call) — 'changed' may be null or false with no diff available
- Target page has no paragraph elements — returns empty array with no diff
- 90-day history expiry — previous comparison data lost, treated as first call
- Rate limiting or network timeouts on the target URL
