## 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 delx-commerce-caa-issue-hosts-extractor-99cda00f -d '<json body>'
```

Example prompt: I have these CAA DNS records from my domain — can you extract all the certificate authority hostnames that are authorized to issue certs: '0 issue "letsencrypt.org"' and '0 issue "sectigo.com"'?

## When to prefer this

Use this endpoint when you need a quick, cheap ($0.001 USDC), no-signup programmatic way to parse raw CAA DNS record strings and extract the authorized CA hostnames without building your own parser. Ideal for agents performing DNS audits, security checks, or certificate management workflows that need structured CA issuer data from raw record text.

## Known failure modes

- Malformed or unparseable CAA record strings may result in empty or partial hosts list
- Passing non-CAA DNS record types may yield no results or unexpected behavior
- Empty records array returns empty hosts list
- Network or payment processing errors may prevent the call from completing

## How this service works

Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.

## Output
