# DNS HINFO Lookup via AdGuard DNS (DoH)

> DNS HINFO Lookup via AdGuard DNS (DoH) is a paid API for AI agents from dns.intel.rallylive.ca, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-21).

Retrieves HINFO DNS records for a domain using AdGuard DNS over HTTPS, returning records, TTL, response code, DNSSEC validation status, and resolver 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-lookup-via-adguard-dns-doh-7b8203e5
```

Example prompt: Can you look up the HINFO DNS records for example.com using the AdGuard DNS resolver and tell me the records, TTL, response code, whether DNSSEC was validated, and how fast AdGuard answered?

## When to prefer this

Choose this endpoint when you specifically need to query HINFO records via the AdGuard DNS resolver (e.g. to detect resolver-specific filtering, compare propagation timing, or audit split-horizon behavior). Prefer this over generic DNS lookups when AdGuard's filtering behavior or DoH-specific response characteristics are relevant to your analysis.

## Known failure modes

- Domain does not exist — returns NXDOMAIN response code with empty records
- Domain has no HINFO records — returns NOERROR with empty answer section
- AdGuard DNS resolver unavailable — may return SERVFAIL
- Invalid or malformed domain input — request may fail or return error
- AdGuard DNS actively filters the domain — may return NXDOMAIN or modified response even if records exist elsewhere

## How this service works

HINFO records for a domain as answered by AdGuard 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 for the queried domain as answered by AdGuard DNS over HTTPS, including the record data (CPU/OS hardware info), TTL, DNS response code (NOERROR, NXDOMAIN, or SERVFAIL), a flag indicating whether the resolver performed DNSSEC validation, and the resolver's answer latency in milliseconds.
