How this service works
Change watch for dkim selector hs1: 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 hs1 selector record value, a boolean indicating whether it has changed since the previous check, a list of fields that changed with their before and after values, and a timestamp of when the record was last seen. Previous results are stored for up to 90 days.
Example use cases
Email deliverability change alert
“Keep an eye on the hs1 DKIM record for mycompany.com and let me know the moment it changes — I want to know exactly what was there before and what it changed to.”
Post-migration DKIM verification
“We just migrated our email provider — can you check if the hs1 DKIM selector for ourstore.com has changed yet from what it was before?”
Security audit DKIM drift detection
“As part of our weekly security audit, check whether the DKIM hs1 selector for clientdomain.com has been modified since last week and show me any before/after differences.”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/watch/dns/dkim/hs1?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to detect changes to a DKIM hs1 selector specifically, rather than just reading its current value. It is ideal for scheduled monitoring workflows where you want an alert-style changed flag and field-level diff rather than raw DNS data. Prefer this over a plain DNS lookup when you need historical comparison built-in without managing state yourself.
Side effects
- Domain has no hs1 DKIM selector record — returns current empty/null result with no previous data to compare
- First-ever call for a domain — no prior state exists so 'changed' cannot be determined and baseline is stored
- DNS lookup failure due to upstream resolver issues — may return error or timeout
- Domain name not provided or malformed — request fails validation
- Cached result older than 90 days — previous state has expired and comparison resets
