dns-sshfp-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).
Retrieves SSHFP DNS records for a domain using DNS.SB as the DoH resolver, returning records, TTL, response code, DNSSEC validation status, and answer latency.

How this service works
SSHFP 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 SSHFP DNS records for the queried domain as answered by DNS.SB, including the record data (algorithm, fingerprint type, fingerprint), TTL, DNS response code (NOERROR, NXDOMAIN, or SERVFAIL), a flag indicating whether DNSSEC was validated by the resolver, and the resolver's answer latency in milliseconds.
Example use cases
Verify SSHFP propagation via DNS.SB
“Has my newly published SSHFP record for ssh.mycompany.com propagated to the DNS.SB resolver yet? Show me the records, TTL, and response code.”
Detect resolver filtering of SSHFP
“I want to know if DNS.SB is filtering or suppressing SSHFP records for openssh.example.org — can you query it and show me what they return, including any SERVFAIL or NXDOMAIN?”
Compare SSHFP resolver latency
“Query SSHFP records for secure.mysite.net through DNS.SB and tell me the answer time so I can compare it against other resolvers for propagation lag.”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/sshfp/via/dnssb?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need to see how the DNS.SB resolver answers SSHFP queries — particularly useful for multi-resolver comparison to detect propagation lag, split-horizon DNS, or resolver-specific filtering. Prefer this over generic SSHFP lookups when DNS.SB's perspective is the variable being tested alongside sibling endpoints (e.g. Google, Cloudflare, OpenDNS variants).
Side effects
- Domain does not exist — returns NXDOMAIN response code with no records
- DNS.SB resolver fails to answer — returns SERVFAIL response code
- Domain has no SSHFP records published — returns NOERROR with empty answer section
- Network timeout reaching DNS.SB DoH endpoint — request may error out
- DNSSEC validation failure — resolver may return SERVFAIL with AD flag unset
