How this service works
DKIM public key for selector "hs2" of a domain: looks up hs2._domainkey.<domain> (TXT, Cloudflare DoH) and parses v=, k=, key type, public-key length, testing flag and whether the key is revoked (empty p=). Confirms that mail signed with the hs2 selector will verify. $0.01 per lookup.
Output
Returns the parsed DKIM TXT record for hs2._domainkey.<domain>, including the protocol version (v=), key type (k=), public key length in bits, whether the key is in testing mode, and whether the key is revoked (empty p= field). Also confirms whether mail signed with the hs2 selector can be expected to verify successfully.
Example use cases
Pre-send DKIM health check
“Before we start our email campaign, can you verify that the hs2 DKIM selector is active and not revoked for ourdomain.com, and tell me the key length?”
Email deliverability audit
“I'm troubleshooting bounce issues — can you look up the hs2 DKIM key for acme.io and tell me if it's valid, what key type it uses, and whether testing mode is enabled?”
Security rotation verification
“We just rotated our DKIM keys — can you confirm that the hs2 selector for mybrand.com now has a new non-empty public key and is no longer revoked?”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/dkim/hs2?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need to inspect the 'hs2' DKIM selector for a domain — for example when auditing email authentication configuration, verifying key rotation, or diagnosing deliverability issues tied to the hs2 selector. Prefer it over generic DNS TXT lookups because it pre-parses DKIM-specific fields (key type, length, revocation status, testing flag) rather than returning raw TXT data.
Side effects
- Domain has no hs2._domainkey TXT record — returns not found or empty result
- DKIM key is revoked (empty p=) — flagged in response but not an API error
- DNS resolution failure via Cloudflare DoH — may return timeout or upstream error
- Malformed TXT record that cannot be parsed into standard DKIM fields
- Invalid or unresolvable domain name supplied as input
