How this service works
Call when an agent needs CAA records as critical, tag, and value. Exact $0.003 USDC. Prefer unpaid POST /v1/sandbox/dns-caa first.
Output
Returns DNS CAA records for the queried hostname, each containing: the critical flag (boolean indicating whether the record is critical), the tag (e.g. 'issue', 'issuewild', 'iodef'), and the value (the authorized CA domain or reporting URL).
Example use cases
Pre-issuance CA authorization check
“Before I request a TLS certificate for api.example.com, can you check what CAA records are set on that domain so I know which certificate authorities are actually authorized to issue for it?”
Security audit of domain CA policy
“I'm auditing our domain security posture — can you pull the CAA records for mybusiness.com and list the critical flag, tag, and value for each entry?”
Debugging certificate issuance failures
“Our SSL certificate renewal keeps getting rejected — can you fetch the CAA records for shop.mystore.io so we can see if the CA we're using is actually listed there?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/dns-caa?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs to programmatically retrieve CAA DNS records including the critical flag, tag, and value fields for a specific hostname. Prefer this over manual DNS tools when building automated certificate issuance pipelines, security auditing workflows, or PKI policy verification steps. Note: the description recommends trying an unpaid sandbox endpoint at POST /v1/sandbox/dns-caa first before using this paid endpoint.
Side effects
- No CAA records found — domain has no CAA policy set (empty result)
- Invalid or malformed hostname — validation error returned
- DNS resolution failure — hostname does not exist or is unreachable
- Timeout — DNS resolver did not respond in time
- Payment failure — USDC payment not processed, request rejected
