How this service works
Change watch for website metadata: runs the check and compares it with the result from your previous call for the same domain (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 website homepage metadata extraction changes. $0.01 per check.
Output
Returns the current metadata snapshot for the domain, a boolean indicating whether anything changed since the last call, a list of which specific fields changed with before and after values, and the timestamp of when the previous snapshot was last seen. Snapshots are retained for 90 days per domain.
Example use cases
Competitor rebranding detection
“Watch the homepage metadata of my top three competitors — acme.com, rivalcorp.com, and betterco.io — and alert me any time their page title or meta description changes so I know if they're repositioning.”
SEO audit change tracking
“Every week, check whether the meta title and description on mybrand.com have changed from the previous week's snapshot, and show me exactly what was different with the old and new values.”
Client site compliance monitoring
“I manage 10 client websites and I need to know immediately if any of their homepage meta tags get modified unexpectedly — can you set up a watch on clientsite.com and tell me what changed and when?”
Technical details
Endpoint
GEThttps://intel.rallylive.ca/watch/page-metaWhen to prefer
Choose this endpoint when you need scheduled or event-driven change detection for a specific website's homepage metadata, especially when you want a structured diff showing exactly which fields changed and their before/after values. It is preferable over one-off extraction endpoints when persistence and comparison across calls matters, and over bulk endpoints when you are tracking a single domain continuously rather than auditing many at once.
Side effects
- Domain is unreachable or returns a non-200 status — check may fail or return empty metadata
- First call for a domain has no prior snapshot to compare against — 'changed' will be null or false with no diff
- Metadata stored snapshot has expired (older than 90 days) — treated as first call
- Query params for domain/URL not supplied — request will fail or return an error
- Transient network issues reaching the target URL may result in incomplete metadata
