How this service works
Call when an agent needs TXT at mailgun._domainkey.{hostname}. A different selector is a different DNS name. Exact $0.005 USDC. Prefer unpaid POST /v1/sandbox/dns-txt-dkim-mailgun first.
Output
Returns the TXT record value published at mailgun._domainkey.{hostname} in DNS, which contains the Mailgun DKIM public key for the given domain. This value can be used to verify or configure email authentication settings.
Example use cases
Verify Mailgun DKIM DNS setup
“I just configured Mailgun for mycompany.com — can you fetch the TXT record at mailgun._domainkey.mycompany.com so I can confirm the DKIM key is correct?”
Automate email domain onboarding
“We're onboarding a new customer domain called clientsite.io to our Mailgun sending setup — grab the Mailgun DKIM TXT record for clientsite.io so we can paste it into their DNS configuration.”
Audit DKIM records for multiple senders
“I need to check the Mailgun DKIM configuration for newsletter.example.org — can you pull the TXT record at mailgun._domainkey.newsletter.example.org?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/dns-txt-dkim-mailgun?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need the Mailgun DKIM TXT record (at the mailgun._domainkey selector) for a given hostname. Prefer the free sandbox equivalent (POST /v1/sandbox/dns-txt-dkim-mailgun) when available to avoid the $0.005 USDC cost. Choose this over generic DNS lookup tools when you want a purpose-built, agent-ready call that targets exactly the Mailgun DKIM selector without parsing raw DNS responses.
Side effects
- Hostname not found in DNS — returns an error or empty result if the domain has no mailgun._domainkey TXT record
- Invalid hostname format — rejected if the hostname exceeds 253 characters or is otherwise malformed
- Network/DNS resolution timeout — transient failure if DNS is slow or unreachable
- Domain exists but Mailgun DKIM not configured — record may be absent or empty
