# DNS DNSKEY Lookup via DNS.SB (DoH)

> DNS DNSKEY Lookup via DNS.SB (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).

Returns DNSKEY records for a domain as answered by the DNS.SB resolver via DNS over HTTPS, including TTL, response code, DNSSEC validation status, and answer latency.

## 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-dnskey-lookup-via-dns-sb-doh-ba89819c
```

Example prompt: Can you look up the DNSKEY records for example.com using DNS.SB and tell me whether DNSSEC was validated and how long the resolver took to answer?

## When to prefer this

Use this endpoint when you specifically need the DNS.SB resolver's view of DNSKEY records — particularly for cross-resolver comparison of DNSSEC key propagation, diagnosing split-horizon DNS, or auditing DNSSEC key rollovers. Prefer it over generic DNS tools when DNSSEC validation status and resolver-specific answer timing are important signals.

## Known failure modes

- Domain does not exist returns NXDOMAIN response code
- SERVFAIL returned if DNS.SB cannot reach authoritative nameservers
- No DNSKEY records published returns empty record set with NOERROR
- Network timeout or DNS.SB resolver outage may delay or block response
- Domain with DNSSEC not enabled returns empty DNSKEY set

## How this service works

DNSKEY 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 DNSKEY record set for the queried domain as seen by DNS.SB, including the raw key records, their TTL, the DNS response code (NOERROR, NXDOMAIN, or SERVFAIL), a boolean indicating whether DNS.SB validated DNSSEC, and the resolver's answer time in milliseconds.
