How this service works
Call when an agent needs TXT at key1._domainkey.{hostname}. A different selector is a different DNS name. Exact $0.001 USDC. Prefer unpaid POST /v1/sandbox/dns-txt-dkim-key1 first.
Output
Returns the raw TXT record value published at key1._domainkey.{hostname} in DNS, typically a DKIM public key string in the format 'v=DKIM1; k=rsa; p=...'
Example use cases
Verify DKIM email authentication setup
“Check if acme-corp.com has a valid DKIM key published at the key1 selector — I want to confirm their email authentication is configured correctly.”
Audit outbound mail signing key
“Can you fetch the DKIM TXT record at key1._domainkey.newsletter.example.com so I can verify which public key they're using to sign outbound emails?”
Debug email deliverability issue
“I'm troubleshooting why emails from startup.io are landing in spam — can you pull the key1 DKIM DNS record for startup.io to see if their public key is published correctly?”
