How this service works
Change watch for dkim selector sendgrid: 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 SendGrid DKIM selector DNS record value, a boolean 'changed' flag indicating whether it differs from the previous call for the same domain, a list of fields that changed with their before and after values, and the timestamp of when the record was last seen. Historical comparisons are retained for 90 days.
Example use cases
Email deliverability change alert
“Watch the SendGrid DKIM selector for mybusiness.com and tell me if anything has changed — I need to know immediately if someone accidentally breaks our email auth setup.”
Post-migration DKIM verification
“We just migrated DNS for clientdomain.com — check whether the SendGrid DKIM selector looks different from what it was before the migration and show me exactly what changed.”
Scheduled security audit monitoring
“Set up a recurring check on the SendGrid DKIM record for ourcompany.com and flag it if the key or any field changes — I want a before-and-after diff every time something shifts.”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/watch/dns/dkim/sendgrid?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to detect changes to a domain's SendGrid DKIM selector over time, rather than just fetching the current value. It is ideal for scheduled monitoring, security alerting, or post-migration validation workflows where knowing what changed (and how) is more important than a one-off lookup. Prefer sibling watch endpoints for other DKIM selectors (e.g. SES, s2) if the domain uses those providers instead.
Side effects
- Domain not found or invalid — returns empty/null DNS result with changed=false
- First-time check for a domain — no previous result to compare against, changed will be false or null
- DNS lookup timeout or Cloudflare DoH error — may return an error or incomplete result
- SendGrid DKIM selector not present on the domain — returns absent/empty record
- Payment not processed — x402 payment required error
