How this service works
Call when an agent needs CAA records whose tag is contactemail. Exact $0.006 USDC. Prefer unpaid POST /v1/sandbox/dns-caa-contactemail first.
Output
Returns the CAA DNS record(s) with the 'contactemail' tag for the given hostname, including the associated contact email address value(s) as published in DNS.
Example use cases
Security contact discovery for a domain
“Find the contact email listed in the CAA DNS records for stripe.com — I need to reach their certificate team.”
Automated certificate issuance compliance check
“Before we request a TLS certificate for api.acme.org, check the CAA contactemail DNS record so we know who to notify about certificate changes.”
Domain audit for CA contact information
“I'm auditing our client domains — can you pull the CAA contactemail record for clientdomain.net so I can verify the right security contact is configured?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/dns-caa-contactemail?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need CAA DNS records filtered to the 'contactemail' tag, such as identifying domain security contacts for certificate management workflows or domain audits. Prefer this over a generic DNS lookup tool when you only need the CAA contactemail tag and want a focused, structured response without parsing raw DNS output.
Side effects
- Hostname does not exist in DNS — returns empty or error response
- No CAA records with contactemail tag exist for the hostname — returns empty result
- Malformed hostname input exceeding 253 characters — schema validation error
- DNS resolution timeout or upstream DNS failure — returns error
- Payment not included — returns 402 Payment Required
