How this service works
Call when an agent needs CAA records whose tag is issue, not issuewild. Exact $0.003 USDC. Prefer unpaid POST /v1/sandbox/dns-caa-issue first.
Output
Returns the CAA DNS records for the given hostname where the tag is 'issue', indicating which certificate authorities are explicitly authorized to issue standard (non-wildcard) certificates for the domain.
Example use cases
Pre-issuance CA authorization check
“Before I request a TLS certificate from Let's Encrypt, can you check the CAA issue records for mybusiness.com to make sure Let's Encrypt is actually authorized to issue certs there?”
Security audit of domain CA policy
“I'm auditing the DNS security configuration for api.acmecorp.net — can you pull all the CAA issue records so I know which certificate authorities are explicitly permitted?”
Troubleshooting certificate issuance failure
“My SSL certificate request for shop.example.org failed and I think it might be a CAA record problem — can you fetch the CAA issue records for that domain so I can see what's configured?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/dns-caa-issue?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need CAA records tagged 'issue' (standard cert issuance, not wildcard). Choose this over general DNS lookup tools when the agent workflow requires a paid, reliable, structured CAA-issue-only result. Use the free sandbox POST /v1/sandbox/dns-caa-issue first for testing before incurring the $0.003 USDC charge.
Side effects
- Hostname not found or does not exist — empty or error response
- Hostname exceeds 253 characters — validation error
- No CAA records present for the hostname — empty result set
- DNS resolution timeout — service may return an error
- Malformed hostname input — request rejected
