How this service works
DKIM public key for selector "20dkim1" of a domain: looks up 20dkim1._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 20dkim1 selector will verify. $0.01 per lookup.
Output
Returns parsed details from the 20dkim1._domainkey.<domain> TXT DNS record, including the DKIM version (v=), key type (k=), public key data, key bit length, whether the key is in testing mode, and whether the key is revoked (empty p= field). Also confirms whether mail signed with the 20dkim1 selector will pass DKIM verification.
Example use cases
Email deliverability audit
“I need to verify that our domain acme.com has a valid and non-revoked DKIM key for the selector 20dkim1 before we start sending our marketing campaign — can you check if the key is set up correctly?”
Security review of DKIM configuration
“Can you inspect the DKIM record for selector 20dkim1 on newco.io and tell me the key type and bit length? I want to make sure we're not using a weak RSA key.”
Diagnosing email authentication failures
“Emails from ourcompany.net are failing DKIM verification — can you look up the 20dkim1 selector DNS record and tell me if the key is revoked or marked as testing-only?”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/dkim/20dkim1?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need to validate the '20dkim1' DKIM selector for a domain, as opposed to generic DKIM checkers. It is ideal for automated email authentication audits, pre-send deliverability checks, security reviews, and diagnosing DKIM failures where the selector in use is known to be 20dkim1. It provides parsed, structured output rather than raw DNS records.
Side effects
- DNS record not found for 20dkim1._domainkey.<domain> — selector not published
- Domain does not exist — NXDOMAIN response
- DKIM record found but key is revoked (empty p= field)
- Malformed TXT record that cannot be parsed
- Network or DoH resolver error
- Missing or invalid domain input parameter
