How this service works
Change watch for is npmjs 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 answer for npmjs.com, a boolean 'changed' flag indicating whether the status differs from the previous call (stored for 90 days), an object listing each field that changed with its before and after values, and a timestamp of when the status was last observed.
Example use cases
Alert on npm registry outage
“Keep watching npmjs.com for me and let me know the moment its up/down status changes from what it was last time — I need to know immediately if the npm registry goes down.”
CI pipeline health gate
“Before kicking off the build, check whether npmjs.com is currently down and whether its status has changed since the last check — block the pipeline if it's newly down.”
Scheduled npm availability digest
“Run a check on npmjs.com right now and compare it to yesterday's result — show me the current status, whether anything changed, what the before and after values were, and when it was last seen.”
Technical details
Endpoint
GEThttps://monitor.intel.rallylive.ca/watch/monitor/is-down/npmjs-com?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need differential/change-aware monitoring of npmjs.com availability rather than a simple one-shot status check — particularly useful for scheduled polling workflows where you want to be alerted only when something changes, avoiding alert fatigue from repeated identical statuses. Prefer over plain uptime checks when you need the before/after diff and a 'changed' boolean to gate downstream actions.
Side effects
- No previous result stored (first call or data expired after 90 days) — 'changed' may be null or undefined
- npmjs.com check itself times out or is unreachable — returns error or indeterminate status
- Payment failure (x402 protocol) — request rejected before check is run
- Stale comparison if caller does not schedule regular polls — changed flag will miss intermediate transitions
