How this service works
Change watch for dkim selector zmail: 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 zmail selector record for the domain, a boolean 'changed' flag indicating whether it differs from the previous check (stored for 90 days), a list of fields that changed with their before and after values, and a timestamp of when the record was last seen.
Example use cases
Email security change alerting
“Monitor the DKIM zmail selector for my domain acmecorp.com and alert me whenever it changes, so I can catch unauthorized key rotations.”
Post-migration DKIM verification
“After we migrated our mail to Zmail, can you watch the DKIM zmail selector for company.io and tell me if the record flips to the new value?”
Third-party domain compliance audit
“I need to track whether any of our partner domains have their zmail DKIM selector changed without notice — start with partner-brand.com and tell me what changed and when.”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/watch/dns/dkim/zmail?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to detect changes to the DKIM zmail selector specifically (not other DKIM selectors or DNS record types), and want a diff with before/after values rather than just the raw record. It is ideal for scheduled polling workflows where you want to be alerted on rotation events, key changes, or tampering over time.
Side effects
- Domain not found or unreachable — DNS resolution failure returned
- No previous check stored — first call returns changed: false with no diff
- 90-day history expired — baseline comparison unavailable
- Invalid or malformed domain input — error response
- Payment not processed — x402 payment required before result returned
