# dns-hinfo-via-opendns

> dns-hinfo-via-opendns 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).

Retrieves DNS HINFO records for a domain via OpenDNS (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-via-opendns-5426489c
```

Example prompt: Look up the HINFO DNS records for example.com using OpenDNS and tell me the records, TTL, response code, whether DNSSEC was validated, and how fast OpenDNS answered.

## When to prefer this

Choose this endpoint when you specifically need to see how OpenDNS resolves HINFO records for a domain, particularly when comparing resolver behavior, detecting filtering or censorship by OpenDNS, checking DNS propagation lag across resolvers, or auditing DNSSEC validation status at OpenDNS specifically. Use sibling endpoints for other resolvers (DNSPod, NextDNS, CleanBrowsing) or other record types.

## Known failure modes

- Domain does not exist — returns NXDOMAIN response code with no record data
- OpenDNS resolver error — returns SERVFAIL response code
- No HINFO records present for domain — returns NOERROR with empty record set
- Invalid or malformed domain name input causes request failure
- Network timeout reaching OpenDNS DoH endpoint

## How this service works

HINFO records for a domain as answered by OpenDNS (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 OpenDNS via DNS over HTTPS, including the record data, TTL, response code (NOERROR, NXDOMAIN, or SERVFAIL), a flag indicating whether DNSSEC validation was performed, and the resolver's answer time in milliseconds.
