How this service works
DKIM public key for selector "mte1" of a domain: looks up mte1._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 mte1 selector will verify. $0.01 per lookup.
Output
Returns parsed DKIM TXT record details for the mte1._domainkey.<domain> record, including the protocol version (v=), key type (k=), RSA/EC key type label, public key bit length, whether the testing flag (t=y) is set, and whether the key is revoked (empty p= field). Confirms whether mail signed with this selector will pass DKIM verification.
Example use cases
Pre-send email authentication audit
“Before we start the email campaign, check if the mte1 DKIM selector is active and valid for ourdomain.com — make sure the key isn't revoked and isn't stuck in testing mode.”
Diagnosing DKIM verification failures
“Emails signed with the mte1 selector from clientdomain.com are failing DKIM verification — can you look up the mte1 DKIM record and tell me what key type and length it's using and whether anything looks wrong?”
New domain onboarding DNS check
“We just onboarded newbrand.com to our mail platform — can you verify that the mte1 DKIM key is published correctly in DNS and that it's not empty or revoked?”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/dkim/mte1?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need to verify or audit the 'mte1' DKIM selector for a domain. It is distinct from generic DKIM checkers in that it targets only the mte1 selector (mte1._domainkey.<domain>) and returns structured, pre-parsed fields rather than raw TXT data. Prefer it for automated email infrastructure audits, pre-deployment checks, or monitoring pipelines where you need machine-readable DKIM metadata for this specific selector.
Side effects
- Domain has no mte1._domainkey TXT record — returns not-found or empty result
- DNS resolution failure via Cloudflare DoH — network or upstream error
- Malformed TXT record that cannot be parsed — partial or error result
- Key is revoked (empty p=) — reported as revoked, not a lookup error
- Payment not provided or insufficient — x402 payment required response
