## How to call it through Zero

```sh
zero fetch --capability cra-agent-dns-lookup-bad1d1fa
```

Example prompt: Look up the live DNS records for api.cra-agent.tech — I want A, AAAA, MX, and TXT records along with their TTLs and whether DNSSEC validates.

## When to prefer this

Use this endpoint when you need real-time, authoritative DNS resolution with DNSSEC validation status for any combination of standard record types. Prefer this over manual dig commands or generic DNS APIs when you need DNSSEC attestation alongside TTL data in a single programmatic call, particularly in security auditing, infrastructure monitoring, or domain configuration verification workflows.

## Known failure modes

- Hostname does not exist (NXDOMAIN) — returns empty or error response
- Invalid record type specified — may return error or be silently ignored
- DNSSEC validation failure for a signed zone — indicates possible tampering or misconfiguration
- Network timeout reaching upstream resolver — transient error
- Malformed hostname input — returns validation error

## How this service works

Live DNS records for a host name, with TTLs and whether the answers validated under DNSSEC. ?type= takes a comma-separated list of A, AAAA, CNAME, MX, TXT, NS, SOA, CAA.

## Output

Returns live DNS records for the queried hostname, including record values, TTL (time-to-live) in seconds, and a DNSSEC validation flag indicating whether the answer was authenticated. Covers record types A, AAAA, CNAME, MX, TXT, NS, SOA, and CAA.
