How this service works
Change watch for webpage text extractor: 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 extract the readable main text of a web page as plain text changes. $0.01 per check.
Output
Returns the current extracted plain text of the page, a boolean indicating whether the content changed since the last call for the same URL, a list of exactly which fields changed with their before and after values, and a timestamp of when the content was last seen. Results from previous calls are retained for 90 days for comparison.
Example use cases
Competitor pricing page monitoring
“Watch https://competitor.com/pricing and tell me whenever the text on that page changes — I want to know immediately if they update their pricing or plans.”
News article edit tracking
“Monitor https://news-site.com/article/breaking-story and alert me if the article text gets edited or updated from what it currently says.”
Government policy page change alerts
“Check https://agency.gov/policies/terms regularly and notify me if the readable content changes at all — I need to stay current on any policy updates.”
Technical details
Endpoint
GEThttps://intel.rallylive.ca/watch/page-textWhen to prefer
Choose this endpoint when you need to detect changes in the human-readable main body text of a webpage on a recurring basis, and want structured diff output (before/after field values) without building your own snapshot storage. It is ideal for scheduled agent workflows that poll pages periodically and need change-aware responses rather than raw content every time.
Side effects
- URL is unreachable or returns a non-200 status — check may fail or return error
- Page requires JavaScript rendering — static extractor may miss dynamically loaded content
- First call for a URL has no previous snapshot to compare against — changed flag may be null or false by default
- URL content is behind authentication — extractor cannot access protected pages
- 90-day retention window exceeded — no prior snapshot available for comparison
