How this service works
HKP service discovery (_hkp._tcp.<domain>): SRV records with priority, weight, port and target host, from Cloudflare DoH. Tells a client where the domain's hkp service lives without guessing hosts. $0.01 per lookup.
Output
Returns SRV record data for the _hkp._tcp.<domain> DNS query, including one or more records each with: priority (lower = preferred), weight (load-balancing hint), port number, and target hostname where the HKP service can be reached. Data is sourced from Cloudflare's DNS over HTTPS resolver.
Example use cases
Locate PGP keyserver for email encryption
“I need to send an encrypted email to someone at protonmail.com — can you find the HKP service details for protonmail.com so I know which keyserver host and port to contact for their public keys?”
Verify keyserver infrastructure for a domain
“We're auditing the DNS setup for gnupg.net — can you pull the _hkp._tcp SRV record so I can see what priority, weight, port, and host they've configured for their keyserver?”
Automate keyserver discovery in key-fetching workflow
“Before fetching a user's public PGP key, I need to know the correct HKP keyserver endpoint for openpgp.org — what does the SRV record say about the host and port?”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/srv/hkp-tcp?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to discover the HKP (HTTP Keyserver Protocol) service location for a domain without hardcoding hostnames or ports. Ideal for agents building OpenPGP key-fetching workflows, email encryption clients, or any application that needs to dynamically resolve a domain's keyserver endpoint via standard DNS SRV records.
Side effects
- No SRV record exists for the domain — returns empty or NXDOMAIN response
- Domain does not exist — DNS resolution fails entirely
- Domain provided without required query parameter — returns validation error
- Cloudflare DoH upstream timeout or outage — may return error or stale result
- Malformed domain input — may return error response
