How this service works
Call when an agent needs TXT at key2._domainkey.{hostname}. A different selector is a different DNS name. Exact $0.002 USDC. Prefer unpaid POST /v1/sandbox/dns-txt-dkim-key2 first.
Output
Returns the raw DNS TXT record value found at key2._domainkey.{hostname}, which typically contains a DKIM public key entry including version, key type, and base64-encoded public key data. Returns an empty or error response if no such record exists.
Example use cases
Email deliverability audit for domain
“Check what DKIM key2 record is published for mailchimp.com — I want to see the TXT content at key2._domainkey.mailchimp.com.”
Verify DKIM key rotation after deployment
“We just rotated our DKIM keys — can you fetch the key2._domainkey TXT record for sendgrid.net and confirm what public key is currently live?”
Diagnose DKIM misconfiguration for client domain
“My client's emails are failing DKIM checks — can you pull the DNS TXT record at key2._domainkey.clientdomain.com so I can see what's actually published there?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/dns-txt-dkim-key2?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need the DKIM key2 selector TXT record for a domain. This is distinct from key1 or other DKIM selectors — the endpoint is hardcoded to the key2._domainkey subdomain. Prefer this over general DNS lookup tools when you want a focused, agent-friendly retrieval of this specific selector without constructing the full subdomain name yourself.
Side effects
- Hostname does not exist — DNS NXDOMAIN response
- No TXT record at key2._domainkey subdomain — empty result
- Invalid or malformed hostname input — validation error
- DNS timeout or resolution failure — transient network error
- Domain exists but key2 selector not configured — no record returned
