How this service works
Change watch for url uptime history: 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 url uptime history changes. $0.01 per check.
Output
Returns the current uptime history result for the URL, a boolean indicating whether it changed since the last call, a list of exactly which fields changed with their before and after values, and the timestamp of when it was last seen. The previous result is retained for 90 days.
Example use cases
Alert on new downtime events
“Set up a scheduled check on https://myshop.com's uptime history and alert me whenever a new downtime event appears in its history that wasn't there before.”
SLA compliance monitoring
“I need to track the uptime history of https://api.myservice.com on a schedule — if the uptime history changes at all, tell me exactly which fields changed and what they changed from and to, so I can verify SLA compliance.”
Vendor reliability tracking
“Monitor the uptime history for https://vendor.thirdparty.io every hour and report back any changes compared to the last check, including what the previous values were versus what they are now.”
Technical details
Endpoint
GEThttps://intel.rallylive.ca/watch/site/status-historyWhen to prefer
Choose this endpoint when you need change-aware uptime history monitoring with before/after diffing built in, rather than just fetching raw current uptime data. It is ideal for scheduled polling workflows where you only want to act when something actually changes, saving downstream processing. It is particularly useful for SLA tracking, vendor reliability monitoring, or alerting pipelines where you need to know precisely what changed and when.
Side effects
- No prior result stored if this is the first call for a URL — changed will be false or undefined
- URL unreachable or invalid returns an error or empty status
- Results expire after 90 days, losing comparison baseline
- Payment failure (x402) blocks the check from running
- Rate limiting if polled too aggressively
