How this service works
HTTP service discovery (_http._tcp.<domain>): SRV records with priority, weight, port and target host, from Cloudflare DoH. Tells a client where the domain's http service lives without guessing hosts. $0.01 per lookup.
Output
Returns the SRV record set for _http._tcp.<domain> queried via Cloudflare DoH, including one or more records each containing: priority (integer), weight (integer), port (integer), and target hostname. Also includes the record TTL and DNS response code.
Example use cases
Discover HTTP service host and port
“Can you find the SRV records for _http._tcp.mycompany.com? I need to know the target host, port, priority, and weight so I can connect to the right server.”
Validate HTTP service configuration
“Check the _http._tcp SRV record for api.startup.io — I want to confirm the HTTP service is pointing to the correct host and port before we go live.”
Automate service endpoint discovery
“For each of these domains, look up their _http._tcp SRV records so I can build a map of where each domain's HTTP service lives — start with platform.example.net.”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/srv/http-tcp?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to discover the exact host and port a domain's HTTP service is served from via standard DNS SRV service discovery, without guessing subdomains. Prefer this over A/AAAA lookups when the domain uses SRV records for service location. Especially useful for federated services, self-hosted infrastructure, or protocols that rely on DNS-SD. Choose this over the OpenDNS SRV variant when you specifically want Cloudflare DoH as the resolver for consistency or privacy reasons.
Side effects
- Domain has no _http._tcp SRV record — returns empty record set or NXDOMAIN
- Malformed domain input — validation error returned
- Cloudflare DoH upstream timeout or error — request may fail with 5xx
- Domain does not exist — NXDOMAIN response code
- Network error between service and Cloudflare DoH resolver
