How this service works
DKIM public key for selector "gmail" of a domain: looks up gmail._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 gmail selector will verify. $0.01 per lookup.
Output
Returns parsed details from the gmail._domainkey.<domain> DNS TXT record including: the DKIM version tag (v=), key type (k=, e.g. rsa), public key length in bits, whether the key is revoked (empty p= field), and whether the testing flag is set. Also confirms whether mail signed with the gmail selector will successfully verify.
Example use cases
Email deliverability audit for Gmail
“I need to verify that acme.com has a properly configured Gmail DKIM key — can you look up its gmail selector and tell me if the key is valid, what type it is, how long it is, and whether it's been revoked?”
Detect revoked Gmail DKIM key
“Can you check if the Gmail DKIM signing key for newsletter.io has been revoked? I want to know if the p= field is empty in the gmail._domainkey record.”
Pre-send email authentication check
“Before we send a campaign through Gmail on behalf of mybrand.com, can you confirm the gmail DKIM selector is live, not in testing mode, and has a valid public key?”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/dkim/gmail?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need to audit or validate the Gmail DKIM selector (gmail._domainkey) for a domain — not generic DKIM selectors. It is ideal for email deliverability checks, security audits of Gmail-routed mail, or confirming that Gmail DKIM signing is correctly configured before sending campaigns. Prefer this over generic DNS TXT lookups when you need structured DKIM field parsing (key type, length, revocation, testing flag) rather than a raw TXT string.
Side effects
- Domain does not exist or has no DNS records — returns NXDOMAIN or empty result
- No gmail._domainkey TXT record found for the domain — selector not configured
- Malformed DKIM TXT record that cannot be parsed — returns parse error
- Cloudflare DoH service unavailable — upstream DNS resolution failure
- Rate limiting or payment failure — HTTP 402 if USDC payment not provided
