How this service works
DKIM public key for selector "default" of a domain: looks up default._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 default selector will verify. $0.01 per lookup.
Output
Returns parsed details from the default._domainkey.<domain> TXT record including the DKIM version tag (v=), key type (k=), public key material, key length in bits, whether the domain is in testing mode, and whether the key has been revoked (empty p= field). Confirms whether mail signed with this selector can be verified.
Example use cases
Email deliverability pre-flight check
“Before we send our campaign, can you verify that example.com's default DKIM selector is properly configured, not revoked, and using a strong key?”
Security audit of outbound mail signing
“I'm auditing our mail infrastructure — can you check the DKIM default selector for acmecorp.com and tell me the key type, length, and whether it's in testing mode?”
Diagnosing DKIM verification failures
“Customers are reporting our emails from newsletter.io aren't passing DKIM checks — can you look up the default DKIM selector and see if the key is revoked or missing?”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/dkim/default?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need to inspect the 'default' DKIM selector for a domain, including key metadata like type, length, testing status, and revocation. Prefer this over generic DNS TXT lookups when you need structured DKIM field parsing rather than raw TXT data. Choose sibling selector-specific endpoints (k1, shopify2, etc.) when targeting other named selectors.
Side effects
- Domain has no default._domainkey TXT record — returns not found or empty result
- Key is revoked (p= is empty) — returned as a parsed flag rather than an error
- DNS lookup failure via Cloudflare DoH — network or upstream error
- Malformed TXT record that cannot be parsed into DKIM fields
- Domain does not exist or is invalid — DNS NXDOMAIN response
