How this service works
Change watch for is port 636 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 state of TCP port 636 on the target host, a boolean 'changed' flag indicating whether the state differs from the previous call, an object listing which fields changed with their before and after values, and a timestamp of when the status was last observed. Previous result is retained for 90 days.
Example use cases
LDAPS exposure alert for security team
“Watch port 636 on 203.0.113.45 and alert me if it goes from closed to open — we need to know immediately if LDAPS becomes unexpectedly reachable from the internet.”
Verify LDAPS server came back online
“Check if port 636 on auth.internal.example.com has changed state since the last check — we had an outage and I want to confirm the LDAPS service is back up.”
Scheduled compliance drift detection
“Run a change watch on port 636 for directory.corp.acme.com and tell me whether the port status has changed since the previous scan, including what it was before and what it is now.”
Technical details
Endpoint
GEThttps://ip.intel.rallylive.ca/watch/ip/port/636?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to detect state changes on TCP port 636 (LDAPS) over time rather than just querying the current status. It is ideal for polling-based alerting workflows, compliance drift detection, or any scenario where you need a before/after comparison rather than a one-shot open/closed answer. Prefer over a plain port-check endpoint when historical comparison and change signaling are required.
Side effects
- Host unreachable or DNS resolution failure — returns an error with no port status
- No previous check stored (first call for this host) — 'changed' may be null or absent; no diff available
- Host rate-limited or firewalled against the probe source — may report port closed even if open
- Payment not processed — request rejected before check is run
- Stale baseline if last check was over 90 days ago — stored result expires and diff cannot be computed
