How this service works
Change watch for is port 143 open: runs the check, compares it with the result from your previous call for the same host (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 open/closed status of port 143, a boolean indicating whether the status changed since the last call for the same host, a before/after diff of any changed fields, and the timestamp of when the previous state was last seen. History is retained for 90 days.
Example use cases
Mail server IMAP downtime alerting
“Watch port 143 on imap.mycompany.com and alert me if it stops being open — I need to know the moment IMAP goes down compared to the last check.”
New server IMAP port go-live detection
“I just set up a new mail server at 198.51.100.42 — check port 143 and tell me as soon as it opens up compared to the previous state.”
Security audit for unexpected IMAP exposure
“Check whether port 143 is open on 203.0.113.15 and tell me if the status changed since the last scan, so I can track if IMAP was unexpectedly exposed.”
Technical details
Endpoint
GEThttps://ip.intel.rallylive.ca/watch/ip/port/143?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need change detection for port 143 specifically — not just a one-off open/closed answer — and want to be alerted when IMAP port availability transitions. Prefer this over a plain port-check endpoint when you are scheduling recurring polls and need the before/after diff returned automatically without managing state yourself.
Side effects
- Host unreachable or invalid hostname — may return an error or closed status
- No previous check stored for this host — 'changed' field may be null or false on first call
- Rate limiting or payment failure for x402 micro-payment — request blocked
- Port scan blocked by firewall at the edge — may report closed when actually filtered
