How this service works
Certificate authority policy lookup for Security review: Return CAA records that constrain certificate issuance. DNS data only; does not send email or verify that an inbox exists.
Output
Returns the CAA (Certification Authority Authorization) DNS records for the specified domain, listing which certificate authorities are permitted to issue TLS/SSL certificates for it. This is pure DNS data — no email verification or inbox checks are performed.
Example use cases
Pre-issuance CA authorization check
“Before I request a TLS certificate from DigiCert for my domain acmecorp.com, can you look up the CAA records to confirm DigiCert is actually authorized to issue certs there?”
Security audit of domain CA policy
“I'm doing a security review — can you pull the CAA DNS records for shopify.com so I can see whether their certificate issuance is locked down to specific authorities?”
Debugging certificate issuance failure
“My Let's Encrypt certificate renewal for myblog.io just failed — can you check the CAA records for myblog.io to see if Let's Encrypt is even permitted to issue certificates for that domain?”
Technical details
Endpoint
POSThttps://market.datapackvibe.com/x402/demand-domain-certificate-authorities-security-review?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically inspect a domain's certificate issuance policy as part of a security review, compliance audit, or pre-issuance validation workflow. It is specifically designed for CAA record lookups — prefer it over general DNS lookup tools when your focus is certificate authority authorization policy. It does not send email, verify inboxes, or perform any active probing beyond DNS.
Side effects
- Domain does not exist in DNS — returns empty or NXDOMAIN-equivalent response
- Domain has no CAA records configured — returns empty record set (meaning any CA can issue)
- Malformed domain input — may return an error or unexpected result
- Network or DNS resolution timeout — transient failure with no data returned
