How this service works
Change watch for dkim selector s3: 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 TXT record for the s3 selector, a boolean 'changed' field indicating whether the record differs from the previous call, a list of fields that changed with before and after values, and the timestamp of when the record was last seen. Previous results are retained for 90 days for comparison.
Example use cases
Alert on unexpected DKIM key rotation
“Keep an eye on the s3 DKIM selector for mycompany.com and ping me if the public key changes — I want to catch any unauthorized key rotation immediately.”
Email deliverability audit scheduling
“Every day, check the s3 DKIM selector for newsletter.example.org and tell me whether it changed, what it was before, and what it is now.”
Post-migration DKIM verification
“We just migrated our email infrastructure — can you check if the s3 DKIM selector for olddomain.com has been updated yet, and show me what changed compared to the previous stored value?”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/watch/dns/dkim/s3?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to continuously monitor the s3 DKIM selector specifically (as opposed to other selectors like 'email', 'mj', or 'protonmail') and want automated change detection with a stored historical baseline rather than a raw one-time DNS lookup. Ideal for scheduling periodic checks via an agent workflow where you need diff output rather than just the current value.
Side effects
- Domain not found or non-existent — returns empty or error result
- DKIM s3 selector TXT record does not exist for the domain — returns no-record result
- First call for a domain has no prior comparison baseline — changed will be false or undefined
- DNS resolution failure via Cloudflare DoH — may return transient error
- Payment not processed — x402 payment required error before result is returned
