How this service works
Change watch for extract h6 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 H6 headings extracted from the page, a boolean `changed` field indicating whether content differs from the previous check, a list of changed fields each with before/after values, and a timestamp of when the page was last seen. Results from previous checks are retained for 90 days.
Example use cases
Track competitor product heading changes
“Keep an eye on the H6 headings at https://competitor.com/pricing — tell me if anything changes compared to the last time you checked, and show me what was different.”
Alert on news section updates
“Monitor the H6 headings on https://news.example.com/latest for me. If any of them have changed since the last check, I want to see the before and after values right away.”
Automated content audit for CMS pages
“Check whether the H6 headings on https://myblog.com/articles have been modified since your last look — return the changed status and any field-level diffs you find.”
Technical details
Endpoint
GEThttps://page.intel.rallylive.ca/watch/page/h6/json?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to detect changes specifically in H6-level headings on a web page over time, rather than full-page diffing or monitoring other element types. It is ideal for scheduled polling workflows where you want lightweight, structured change detection with field-level before/after diffs stored for up to 90 days, and you are willing to pay $0.02 per check via x402.
Side effects
- Target URL is unreachable or returns non-200 status — check may fail or return empty extraction
- First-time call for a URL has no prior result to compare against — changed may be null or false by default
- Page blocks scrapers via robots.txt, CAPTCHA, or bot detection — extraction may be empty or incorrect
- 90-day retention window exceeded — previous snapshot no longer available for comparison
- H6 elements are dynamically rendered via JavaScript and not present in raw HTML — extraction may miss them
