How this service works
Change watch for is duolingo com down: runs the check, compares it with the result from your previous call for the same query (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 up/down status of duolingo.com, a boolean 'changed' field indicating whether the result differs from the previous call, a list of fields that changed with their before and after values, and the timestamp of when the status was last observed. Previous results are retained for 90 days per query.
Example use cases
Outage alert for Duolingo users
“Set up a watch on duolingo.com so I get notified the second it goes down — I need to know immediately if the site becomes unavailable.”
Recovery detection after known outage
“Duolingo was down earlier — can you check if its status has changed back to up since the last time I checked?”
Scheduled uptime monitoring workflow
“Run a recurring check on duolingo.com every 5 minutes and tell me whenever its status changes, including what specifically changed and what it looked like before.”
Technical details
Endpoint
GEThttps://monitor.intel.rallylive.ca/watch/monitor/is-down/duolingo-com?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need change-aware monitoring of duolingo.com specifically — not just a raw status check, but delta detection that tells you whether anything is different from the last observation. Ideal for agents that need to fire alerts only on state transitions rather than polling raw status on every check. Best when integrated into a scheduled workflow where repeated calls compare against stored prior state.
Side effects
- Network timeout reaching duolingo.com from edge — may return error or stale data
- No previous check stored yet for this query — 'changed' may be null or undefined on first call
- Duolingo.com returns unexpected HTTP status that doesn't map cleanly to up/down
- Payment failure ($0.02 USDC) causes the check not to execute
- Rate limiting or throttling on the monitoring endpoint itself
