How this service works
Change watch for dkim selector k1: 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 k1 selector record value, a boolean indicating whether it changed since the previous call for that domain (baseline kept 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
Alert on unauthorized DKIM key rotation
“Keep an eye on the DKIM k1 selector for mybusiness.com and alert me immediately if the public key or any other field changes — I want to know as soon as someone rotates or tampers with it.”
Validate DKIM deployment went live
“I just updated the DKIM k1 DNS record for newsletter.example.com — can you check if it has changed compared to what you saw last time and confirm the new value is now live?”
Scheduled email security audit
“Run a change check on the DKIM k1 selector for clientdomain.io and tell me whether it changed, what the current record looks like, and when it was last seen — I'm auditing their email security configuration.”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/watch/dns/dkim/k1?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need ongoing change detection specifically for the DKIM selector k1 DNS record, rather than a one-time lookup. It is ideal for scheduling periodic checks to detect unauthorized key rotations, validate that a new DKIM key has propagated, or audit email authentication configuration changes over time. Prefer this over a plain DKIM lookup when you need the before/after diff and change history.
Side effects
- Domain not found or invalid domain name provided — returns an error or empty record
- No prior baseline exists (first call for a domain) — changed may be false or indeterminate
- DKIM k1 selector does not exist for the domain — returns NXDOMAIN or empty record response
- DNS resolution failure or upstream resolver unavailable — may return timeout or error
- Payment not processed — request blocked with 402 response
