How this service works
Change watch for dkim selector selector2: 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 selector2 record value, a boolean indicating whether it changed since the last check (stored up to 90 days), the specific fields that changed with before/after values, and the timestamp of when the record was last seen.
Example use cases
DKIM key rotation alerting
“Watch the DKIM selector2 record for mybusiness.com and alert me the moment it changes — I need to know immediately if someone rotates or tampers with our email signing key.”
Email deliverability audit
“Check whether the DKIM selector2 record for acmecorp.com has changed since the last time you looked, and show me exactly what fields were different and when it was last seen.”
Ongoing third-party domain monitoring
“Set up a recurring watch on the DKIM selector2 DNS record for clientdomain.net so I can track any changes over time and catch unauthorized modifications.”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/watch/dns/dkim/selector2?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need change-detection semantics for DKIM selector2 specifically — it compares against a stored 90-day history and returns a structured diff, making it ideal for scheduled monitoring and alerting workflows. Prefer it over a plain DKIM lookup when you care about detecting key rotations or unauthorized record modifications rather than just the current value.
Side effects
- Domain not found or does not have a DKIM selector2 record — returns empty or NXDOMAIN result
- First-ever call for a domain has no previous result to compare against, so 'changed' may be indeterminate
- DNS propagation delays may cause transient mismatches
- Payment failure (x402) if USDC balance is insufficient — call not executed
