## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability certificate-authority-policy-lookup-caa-dns-records-5588c06a -d '<json body>'
```

Example prompt: Can you look up the CAA DNS records for example.com so I can see which certificate authorities are allowed to issue TLS certificates for it?

## When to prefer this

Use this endpoint when you need to programmatically query CAA DNS records for IT administration, security auditing, or pre-issuance checks. Prefer this over manual DNS tools when automating certificate lifecycle management, running compliance audits across multiple domains, or when an AI agent needs structured CAA data for decision-making. Not suitable for email verification or certificate issuance itself.

## Known failure modes

- Domain has no CAA records (returns empty result, meaning any CA is implicitly allowed)
- Invalid or non-existent domain name returns a DNS lookup error
- Malformed domain input triggers a validation error
- Transient DNS resolution failures may occur for newly registered or propagating domains

## How this service works

Certificate authority policy lookup for IT administration: 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 queried domain, showing which certificate authorities are explicitly permitted to issue TLS/SSL certificates. The response contains DNS record data only — no email verification or inbox checks are performed.
