How this service works
Call when an agent needs TXT at selector1._domainkey.{hostname}. A different selector is a different DNS name. Exact $0.01 USDC. Prefer unpaid POST /v1/sandbox/dns-txt-dkim-selector1 first.
Output
Returns the raw TXT record string found at selector1._domainkey.{hostname} in DNS, typically containing a DKIM public key entry (e.g. v=DKIM1; k=rsa; p=MIIBIjAN...). Returns an error or empty result if no record exists.
Example use cases
Email deliverability audit
“Check whether example.com has a valid DKIM TXT record published at selector1._domainkey — I need to confirm our DKIM signing key is live in DNS.”
Third-party domain onboarding check
“I'm onboarding a new sender domain, acme-corp.com — can you pull the selector1 DKIM TXT record to verify they've published their public key correctly?”
Security investigation of a suspicious sender
“I got a suspicious email allegedly from notifications.bigbank.com — can you look up the DKIM TXT record at selector1._domainkey.notifications.bigbank.com to see what public key they're publishing?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/dns-txt-dkim-selector1?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need to resolve the selector1 DKIM TXT record for a given domain, for purposes such as email authentication validation, deliverability auditing, or security investigation. It is purpose-built for the selector1._domainkey subdomain lookup; for other selectors (e.g. selector2, google, mail), a different DNS TXT endpoint would be needed.
Side effects
- Hostname does not have a selector1 DKIM TXT record published — returns empty or not-found response
- Invalid or malformed hostname input causes validation error
- DNS resolution timeout or upstream failure
- Private/reserved hostnames may be rejected
- Hostname exceeds 253-character limit
