## How to call it through Zero

```sh
zero fetch --capability dns-naptr-via-mullvad-1dd08e51
```

Example prompt: Can you look up the NAPTR records for example.com using Mullvad's DNS over HTTPS resolver and tell me what records come back, the TTL, whether DNSSEC was validated, and how fast the resolver responded?

## When to prefer this

Use this endpoint when you specifically need NAPTR records resolved through Mullvad's DNS over HTTPS resolver — particularly for privacy-sensitive lookups, for comparing Mullvad's answers against other resolvers (e.g., Cloudflare, Google, CleanBrowsing) to detect propagation lag, DNS filtering, or split-horizon configurations, or when you need DNSSEC validation status from a privacy-focused resolver.

## Known failure modes

- Domain not found returns NXDOMAIN response code
- Resolver failure returns SERVFAIL response code
- Missing or invalid domain parameter results in a request error
- Network timeout if Mullvad DoH endpoint is unreachable
- DNSSEC validation failure flagged in response but still returns records if available

## How this service works

NAPTR records for a domain as answered by Mullvad DNS (DNS over HTTPS): the records, TTL, response code (NOERROR/NXDOMAIN/SERVFAIL), whether the resolver validated DNSSEC, and the resolver's answer time. Compare resolvers to spot propagation lag, filtering or split-horizon answers. $0.01 per lookup.

## Output

Returns NAPTR DNS records for the queried domain as answered by Mullvad's DNS over HTTPS resolver, including the record set, TTL, response code (NOERROR, NXDOMAIN, or SERVFAIL), a boolean indicating whether DNSSEC was validated, and the resolver's answer time in milliseconds.
