How this service works
Change watch for dkim selector pm: runs the check, compares it with the result from your previous call for the same domain (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 DKIM pm selector record value, a boolean 'changed' flag indicating whether it differs from the previous call (stored up to 90 days), a list of fields that changed with their before and after values, and the timestamp of when the record was last seen.
Example use cases
Alert on DKIM key rotation
“Watch the pm DKIM selector for sendgrid-customer.com and ping me whenever it changes — I need to know the before and after values so I can update our mail signing config.”
Email deliverability audit monitoring
“I'm auditing email infrastructure for clientdomain.io — can you periodically check if the pm DKIM selector has changed and flag any differences since the last check?”
Security drift detection for DKIM
“Set up a watch on the pm._domainkey DNS record for mybusiness.com so I get alerted if anyone rotates or removes the DKIM key unexpectedly — show me what changed.”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/watch/dns/dkim/pm?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to continuously monitor the pm DKIM selector for a specific domain and be alerted to changes over time, rather than just doing a one-time lookup. It is ideal for scheduled polling workflows where detecting key rotation, record removal, or value drift matters for email deliverability or security compliance. Prefer this over a plain DKIM lookup endpoint when before/after change detection and historical comparison are required.
Side effects
- Domain does not have a pm DKIM selector record — returns current state with no record found
- First-time call for a domain has no previous result to compare against — changed will be false or null with no diff
- Domain name is invalid or unresolvable — lookup fails with an error
- 90-day retention window expired — no previous result available for comparison
- Network or DNS resolution error — transient failure with no result returned
