How this service works
Change watch for is kayak 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 kayak.com, a boolean 'changed' flag 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. Results are compared against a stored snapshot retained for 90 days.
Example use cases
Travel app outage alerting
“Watch kayak.com for me and alert me the moment it goes down or recovers — I need to know right away if my travel booking site has an outage.”
Scheduled uptime status check
“Run a check on kayak.com every 15 minutes and tell me each time the up/down status changes compared to the last check.”
Post-deploy site recovery confirmation
“After our routing changes, keep polling kayak.com and let me know as soon as it flips from down to up so I can confirm the fix worked.”
Technical details
Endpoint
GEThttps://monitor.intel.rallylive.ca/watch/monitor/is-down/kayak-com?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to detect transitions in kayak.com availability rather than just its current status. It is ideal for event-driven alerting workflows where you only want to act when something changes. Prefer it over a simple status-check endpoint when you want before/after field diffs and a 90-day historical comparison window.
Side effects
- No previous check stored — first call has nothing to compare against so 'changed' may default to false or null
- kayak.com is unreachable due to a network issue unrelated to its actual status, causing a false positive
- Stored snapshot is older than 90 days and has expired, losing comparison baseline
- Payment not fulfilled — x402 micropayment of $0.02 USDC not completed, request rejected
