## 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 sitesignal-public-dns-record-inventory-960f2c9d
```

Example prompt: Pull up all the public DNS records for github.com — I want to see the A, MX, TXT, NS, and SOA entries so I can understand how their DNS is configured.

## When to prefer this

Choose this endpoint when you need a comprehensive, multi-record-type DNS snapshot for a single domain in one call, rather than querying individual record types separately. It is particularly useful for auditing, documentation, pre-migration checks, email deliverability troubleshooting, or security assessments where you need to see the full DNS posture of a hostname at once.

## Known failure modes

- Domain does not exist (NXDOMAIN) — returns empty or error response
- Domain has no records of a specific type — those record types may be omitted or return empty arrays
- Invalid hostname or malformed URL input — likely returns a 400-level error
- Temporary DNS resolution failure — may return partial results or timeout
- Private or internal hostnames not resolvable from public DNS — no results returned

## How this service works

Inventory bounded public DNS answers for A, AAAA, CNAME, NS, MX, TXT, CAA, HTTPS SRV, and SOA record types.

## Output

Returns a structured inventory of all observed public DNS record types for the queried domain, including A (IPv4 addresses), AAAA (IPv6 addresses), CNAME (aliases), NS (nameservers), MX (mail exchangers), TXT (text records including SPF/DKIM/DMARC), CAA (certificate authority authorizations), HTTPS, SRV (service records), and SOA (start of authority). Results are bounded to a single DNS resolution pass.
