## 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 dns-caa-issuewild-record-lookup-fdf83f4c -d '<json body>'
```

Example prompt: What are the CAA issuewild DNS records for example.com? I need to know which certificate authorities are authorized to issue wildcard TLS certificates for that domain.

## When to prefer this

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.

## Known failure modes

- 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

## 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.
