How this service works
DKIM public key for selector "y1" of a domain: looks up y1._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 y1 selector will verify. $0.01 per lookup.
Output
Returns parsed details from the y1._domainkey.<domain> TXT record including the DKIM version tag (v=), key type (k=, e.g. rsa or ed25519), 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 y1 selector will successfully verify.
Example use cases
Email deliverability pre-flight check
“Before I send our campaign, can you verify that the y1 DKIM selector on ourdomain.com is properly configured and not revoked, so emails will actually pass DKIM verification?”
Security audit of DKIM key strength
“I need to audit our email security — can you look up the y1 DKIM selector for acmecorp.com and tell me the key type and public key length so I can check if it meets current security standards?”
Troubleshooting DKIM signing failures
“Our transactional emails signed with the y1 selector keep failing DKIM — can you pull the y1._domainkey TXT record for startupxyz.io and tell me if the key looks valid or if it might be revoked or misconfigured?”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/dkim/y1?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need to inspect or validate the DKIM selector named 'y1' for a domain — as opposed to other common selectors like 'default', 'google', or 'selector1'. Prefer this over generic DNS TXT lookup tools when you need structured DKIM-specific parsing (key type, length, revocation status, testing flag) rather than raw TXT record data. Ideal for automated email security audits, pre-send deliverability checks, or monitoring DKIM key rotation for domains that use the y1 selector naming convention.
Side effects
- Domain does not have a y1._domainkey TXT record — returns not found or empty result
- DNS resolution failure via Cloudflare DoH — may return a timeout or upstream error
- Malformed TXT record that cannot be parsed — may return a parse error
- Domain does not exist — NXDOMAIN response
- Payment failure or insufficient balance — 402 Payment Required before lookup is performed
