How this service works
Call when an agent needs CAA records whose tag is issuewild. Exact $0.004 USDC. Prefer unpaid POST /v1/sandbox/dns-caa-issuewild first.
Output
Returns the CAA DNS records with the 'issuewild' tag for the queried hostname, identifying which certificate authorities are permitted to issue wildcard TLS/SSL certificates for that domain.
Example use cases
Wildcard cert CA authorization audit
“Check the CAA issuewild records for mycompany.com — I need to know exactly which certificate authorities are permitted to issue wildcard TLS certificates for that domain.”
Pre-issuance wildcard cert validation
“Before I request a wildcard TLS cert for *.api.example.org, can you look up the CAA issuewild DNS records to confirm my CA is actually authorized to issue it?”
Security policy review for subdomain
“Pull the CAA issuewild records for shop.acme.io — our security team wants to verify no unauthorized CAs are listed as allowed to issue wildcard certificates for that hostname.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/dns-caa-issuewild?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need CAA records filtered to the 'issuewild' tag, which governs wildcard certificate issuance authority. Prefer the free sandbox POST /v1/sandbox/dns-caa-issuewild endpoint when testing. Choose this over generic DNS lookup tools when you need structured, tag-filtered CAA data without parsing raw DNS output.
Side effects
- Hostname does not exist or has no CAA records — returns empty result or not-found response
- Malformed hostname input (exceeds 253 characters or is empty) — validation error
- DNS resolution timeout or upstream DNS failure — service error
- Payment failure — 402 response if USDC payment is not provided or insufficient
