# dns-hinfo-via-dnssb

> dns-hinfo-via-dnssb 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).

Fetches HINFO DNS records for a domain using DNS.SB as the DNS-over-HTTPS resolver, returning records, TTL, response code, DNSSEC validation status, and answer time.

## 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-dnssb-299b9942
```

Example prompt: Look up the HINFO records for example.com using DNS.SB as the resolver and tell me the TTL, response code, whether DNSSEC was validated, and how long the answer took.

## When to prefer this

Use this endpoint when you specifically need HINFO records resolved via DNS.SB as the resolver — for example, to compare DNS.SB's answer against other resolvers (Cloudflare, Google, Mullvad) to detect propagation delays, split-horizon DNS, or resolver-level filtering. Prefer this over generic DNS lookups when DNSSEC validation status and resolver answer time are important signals.

## Known failure modes

- Domain does not exist — returns NXDOMAIN response code with no records
- DNS.SB resolver is unreachable or times out — returns SERVFAIL response code
- No HINFO records configured for the domain — returns NOERROR with empty answer section
- Invalid or malformed domain name input — likely returns an error or SERVFAIL
- Network issues between the API and DNS.SB resolver — may result in timeout or SERVFAIL

## How this service works

HINFO records for a domain as answered by DNS.SB (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 records for the queried domain as seen by the DNS.SB resolver, including the record data, TTL, DNS response code (NOERROR, NXDOMAIN, or SERVFAIL), whether the resolver validated DNSSEC, and the answer time in milliseconds.
