How this service works
DKIM public key for selector "1" of a domain: looks up 1._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 1 selector will verify. $0.01 per lookup.
Output
Returns parsed details from the DKIM TXT record at 1._domainkey.<domain>, including: DKIM version (v=), key type (k=, e.g. rsa or ed25519), the raw public key, public key bit length, whether the testing flag is set, and whether the key is revoked (empty p= field). Indicates if mail signed with the '1' selector will pass verification.
Example use cases
Pre-send email deliverability check
“Before we send our marketing campaign, can you verify that DKIM selector 1 is properly set up and not revoked on ourdomain.com so the emails won't fail authentication?”
Security audit of DKIM configuration
“I'm auditing our domain acmecorp.com — can you pull the DKIM public key for selector 1 and tell me the key length, key type, and whether it's in testing mode or revoked?”
Troubleshooting DKIM verification failures
“Our emails from newsletter.io are failing DKIM checks — can you look up the DKIM record for selector 1 on newsletter.io and tell me exactly what's in the record so I can figure out what's wrong?”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/dkim/1?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need to verify or inspect the DKIM configuration for the selector named '1' — a common default selector used by many email service providers and self-hosted mail servers. Choose this over generic DNS TXT lookups because it automatically parses all DKIM-specific fields (key type, length, testing flag, revocation) rather than returning raw text.
Side effects
- Domain does not exist — DNS lookup fails with NXDOMAIN
- No DKIM record found at 1._domainkey.<domain> — record missing
- DKIM record is malformed and cannot be parsed
- Empty p= field — key is revoked, verification will fail
- Cloudflare DoH timeout or network error
- Domain input missing or invalid format
