How this service works
DKIM selector lookup for Vendor screening: Look up a supplied DKIM selector under _domainkey. DNS data only; does not send email or verify that an inbox exists.
Output
Returns raw DNS TXT record data for the specified DKIM selector under the _domainkey subdomain of the given domain, including the public key and policy fields if the record exists. Does not send email or verify inbox existence.
Example use cases
Vendor onboarding email security check
“Before we onboard TechVendor Inc., can you check if their domain techvendor.com has a valid DKIM record for the selector 'default'? I want to make sure they have proper email authentication in place.”
Supplier email spoofing risk audit
“I'm auditing our supplier list for email spoofing risks. Can you look up the DKIM selector 'mail' under the _domainkey DNS records for supplierco.com and tell me what you find?”
Procurement security screening
“We're screening a new contractor whose domain is contractorpartner.net — can you query DNS to check if their DKIM selector 'k1' is properly published so we know their emails aren't spoofable?”

Endpoint
POSThttps://market.datapackvibe.com/x402/demand-domain-dkim-selector-check-vendor-screening?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to perform DNS-level DKIM record validation for a specific domain and selector, particularly in vendor screening, supplier onboarding, or email security audit workflows. It is appropriate when you only need raw DNS data — not full email deliverability analysis or inbox verification.
Side effects
- Domain does not exist in DNS — returns NXDOMAIN or empty result
- Selector not found — no TXT record exists at selector._domainkey.domain
- Malformed domain input — validation error
- DNS timeout or resolution failure — transient network error
- Selector string is empty or invalid — bad request error
