How this service works
Change watch for dkim selector dkim: 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 'dkim' selector TXT record value, a boolean indicating whether it changed since the last check (stored for 90 days), a list of fields that changed with before and after values, and a timestamp of when the record was last seen.
Example use cases
DKIM key rotation alert for SaaS platform
“Watch the DKIM 'dkim' selector record for myapp.com and let me know immediately if it changes — I need to catch any unauthorized key rotation.”
Email deliverability monitoring for client domain
“Check if the DKIM 'dkim' selector DNS record for clientdomain.com has changed from what you last saw, and show me the before and after values if it has.”
Scheduled DKIM drift detection
“Set up a recurring check on the DKIM 'dkim' selector for ourdomain.com so you alert me whenever that record changes — I want to know the exact fields that changed and what they changed from and to.”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/watch/dns/dkim/dkim?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to detect changes to the 'dkim' DKIM selector specifically (not other selectors like google, protonmail3, etc.) and want a built-in diff with before/after values and a 90-day history. Prefer it over raw DNS lookups when you need automated change detection and alerting rather than just the current record value.
Side effects
- Domain has no dkim._domainkey TXT record — returns empty or null result
- No previous check stored (first call) — changed may be false or baseline set without comparison
- Domain does not exist or is unreachable via DNS — DNS resolution error
- Previous check data expired (older than 90 days) — comparison treated as new baseline
- Network timeout reaching Cloudflare DNS resolver — transient error
