## 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 domain-and-dns-checks-full-dns-record-lookup-3667e4d0
```

Example prompt: Can you pull all the DNS records for example.com — I need the A, AAAA, NS, MX, TXT, and CAA records along with their TTLs and whether the domain actually exists?

## When to prefer this

Choose this endpoint when you need a comprehensive, single-call snapshot of all major DNS record types for a domain, including TTLs and existence confirmation. It is ideal over record-type-specific endpoints when you want a full DNS audit in one request, or when you don't know in advance which record types are present. Use sibling endpoints (e.g. MX-only, DNSSEC, CAA) when you need deeper analysis of a specific record type.

## Known failure modes

- Domain does not exist — exists field returns false with reasons
- DNS lookup partially fails — degraded flag set to true, notChecked lists missing record types
- Invalid domain name format — likely a 4xx client error
- Upstream DNS resolver unavailable — possible 5xx or timeout
- No records of a specific type — array returns null or empty for that record type

## How this service works

A, AAAA, NS, MX, TXT and CAA records of a domain in one call, with TTLs and whether it exists.

## Output

Returns a structured object containing all major DNS record types (A, AAAA, NS, MX, TXT, CAA) with values and TTLs, a boolean indicating whether the domain exists, a verdict and summary string, a timestamp (asOf), source information, and optional flags for degraded lookups or unchecked record types.
