How this service works
Change watch for tracker detect: 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 tracker and analytics detection on a page changes. $0.01 per check.
Output
Returns the current tracker/analytics detection result for the URL, a boolean indicating whether anything changed since the last check (stored up to 90 days), a detailed diff of exactly which fields changed with before and after values, and a timestamp of when the page was last seen.
Example use cases
Competitor analytics monitoring
“Watch https://competitor.com/pricing every day and alert me whenever they add or remove any tracking or analytics tools — I want to see exactly which trackers changed and what they looked like before.”
Privacy compliance auditing
“Monitor https://myapp.com/checkout on a schedule and tell me if any new third-party trackers appear or existing ones disappear since the last check, so I can make sure we stay compliant.”
Client site change detection
“Set up a recurring check on https://clientsite.com and flag it immediately if the tracker or analytics setup changes — include what was there before and what it looks like now.”
Technical details
Endpoint
GEThttps://intel.rallylive.ca/watch/site/trackersWhen to prefer
Choose this endpoint when you need to detect changes in tracker and analytics scripts over time rather than just a point-in-time snapshot. It is ideal for scheduled monitoring workflows where you want to be alerted only when something actually changes, with a precise before/after diff rather than re-analyzing raw results manually. Prefer it over a one-shot tracker detector when continuity and change detection across calls is required.
Side effects
- URL unreachable or returns non-200 status — may return an error or empty result
- No previous check stored for the URL (first call) — 'changed' will be false or undefined with no diff
- URL is paywalled or bot-protected — tracker detection may be incomplete
- Stale baseline if prior check is older than 90 days — history is dropped and baseline resets
- Malformed or missing URL parameter — returns validation error
