How this service works
DKIM public key for selector "cc" of a domain: looks up cc._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 cc selector will verify. $0.01 per lookup.
Output
Returns parsed details from the cc._domainkey.<domain> TXT record including: v= version tag, k= key type (e.g. rsa), public key length in bits, whether the testing flag is set, and whether the key is revoked (empty p= field). Also confirms whether mail signed with the cc selector will successfully verify.
Example use cases
Diagnose CC selector email failures
“Emails signed with the 'cc' DKIM selector from acme.com keep failing — can you look up the cc DKIM record for acme.com and tell me if the key is valid, revoked, or misconfigured?”
Audit DKIM before domain migration
“Before we migrate our domain sendgrid.net, can you pull the DKIM public key for the cc selector and tell me the key type, its length, and whether it's in testing mode?”
Verify new DKIM cc selector publish
“I just published a new DKIM key for the cc selector on mybrand.io — can you confirm it's resolving correctly in DNS and that the key isn't empty or revoked?”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/dkim/cc?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need to inspect the 'cc' DKIM selector for a domain — for example when diagnosing DKIM failures from a service that uses the cc selector, auditing domain email security posture, or confirming a newly published cc DKIM key. Prefer this over generic DNS TXT lookups because it automatically parses all DKIM-specific fields and flags revocation and testing states.
Side effects
- Domain has no cc._domainkey TXT record — returns not found or empty result
- Key is revoked (empty p= field) — returns revoked status
- DNS resolution fails via Cloudflare DoH — returns lookup error
- Malformed TXT record that cannot be parsed — returns parse error
- Domain does not exist — returns NXDOMAIN or equivalent
- Rate limiting or payment failure for $0.01 USDC charge
