# dns-hinfo-via-mullvad

> dns-hinfo-via-mullvad is a paid API for AI agents from dns.intel.rallylive.ca, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-22).

Looks up HINFO DNS records for a domain using Mullvad's DNS over HTTPS resolver, returning records, TTL, response code, DNSSEC validation status, and answer time.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 dns-hinfo-via-mullvad-c06a403f
```

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

## When to prefer this

Use this endpoint when you specifically need to see how Mullvad's privacy-focused DNS over HTTPS resolver answers HINFO queries, particularly for comparing resolver behavior, detecting split-horizon DNS, checking for DNS filtering by Mullvad, or auditing DNSSEC validation. Prefer this over generic DNS tools when resolver identity and answer metadata (TTL, response time, DNSSEC flag) are important.

## Known failure modes

- Domain does not exist — returns NXDOMAIN response code with no records
- Resolver error — returns SERVFAIL if Mullvad cannot resolve the query
- No HINFO records exist for the domain — NOERROR with empty record set
- Network timeout reaching Mullvad DNS endpoint — request may fail or return error
- Invalid domain format in query — may return error or unexpected response

## How this service works

HINFO 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 the HINFO DNS records found (if any), the TTL of those records, the DNS response code (NOERROR, NXDOMAIN, or SERVFAIL), whether Mullvad validated DNSSEC for the response, and the resolver's answer time in milliseconds.
