How this service works
Call when an agent needs TXT at selector2._domainkey.{hostname}. A different selector is a different DNS name. Exact $0.001 USDC. Prefer unpaid POST /v1/sandbox/dns-txt-dkim-selector2 first.
Output
Returns the raw TXT record string published at selector2._domainkey.{hostname} in DNS, typically containing a DKIM public key in the format v=DKIM1; k=rsa; p=<base64-public-key>.
Example use cases
Verify DKIM email authentication setup
“Can you check the DKIM selector2 TXT record for mailgun.org? I want to confirm the public key is properly published at selector2._domainkey.mailgun.org.”
Email deliverability audit for a client domain
“I'm auditing email configuration for acmecorp.com — please fetch the selector2 DKIM TXT record so I can confirm their DKIM signing key is in place.”
Diagnose DKIM misconfiguration
“Emails from sendgrid.net are being flagged as spam — can you pull the DKIM selector2 TXT record for sendgrid.net to see if the public key looks correct?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/dns-txt-dkim-selector2?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need the selector2 DKIM TXT record for a given hostname. Prefer the free sandbox endpoint (POST /v1/sandbox/dns-txt-dkim-selector2) if available before paying. Use this paid endpoint when the sandbox is unavailable or rate-limited. If you need selector1 or a differently named selector, use the corresponding endpoint for that selector.
Side effects
- No TXT record found at selector2._domainkey.{hostname} — domain may not have selector2 DKIM configured
- Invalid or malformed hostname input
- DNS resolution timeout or upstream DNS failure
- hostname exceeds 253 characters or is empty
