How this service works
Change watch for extract nav 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 navigation extracted as JSON, a boolean 'changed' flag indicating whether the nav differs from the previous call for the same URL, a list of fields that changed with before and after values, and the timestamp of when it was last seen. Results from previous calls are retained for 90 days for comparison.
Example use cases
Competitor site nav monitoring
“Watch the navigation on https://competitor.com and alert me whenever they add or remove items — I want to know exactly what changed and what it looked like before.”
Client website audit trail
“Check the nav structure on https://myclient.com and compare it to the last snapshot — tell me if changed is true and show me the before and after for any fields that differ.”
Automated site change detection
“Schedule a regular check on https://storefront.example.com's navigation and notify me the moment any nav links are updated or rearranged.”
Technical details
Endpoint
GEThttps://page.intel.rallylive.ca/watch/page/nav/json?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to detect and diff changes in a web page's navigation structure over time, rather than a one-shot extraction. It is purpose-built for change monitoring with built-in before/after comparison and a 90-day history window, making it ideal for scheduled alerting workflows. Prefer it over a plain nav extraction endpoint when the goal is to track what changed, not just what the nav currently looks like.
Side effects
- URL is unreachable or returns a non-200 status — no nav data returned
- No previous snapshot exists for the URL — changed flag may be null or false on first call
- Navigation is rendered via JavaScript and not present in static HTML — extraction may be incomplete
- Payment of $0.02 USDC not fulfilled — request rejected
- Rate limits or network timeouts on the target page
