How this service works
HTTPS service discovery (_https._tcp.<domain>): SRV records with priority, weight, port and target host, from Cloudflare DoH. Tells a client where the domain's https service lives without guessing hosts. $0.01 per lookup.
Output
Returns one or more SRV DNS records for _https._tcp.<domain>, each containing: priority (lower = preferred), weight (load-balancing hint), port number, and target hostname — sourced via Cloudflare DNS over HTTPS.
Example use cases
Locate HTTPS service before connecting
“Before my app tries to connect to api.acmecorp.com, can you check the _https._tcp SRV record so I know the exact host and port I should be hitting?”
Audit service discovery configuration
“We're auditing our DNS setup — can you pull the _https._tcp SRV record for mycompany.com and tell me the priority, weight, port, and target host?”
Debug missing HTTPS SRV record
“Our HTTPS clients can't auto-discover the service endpoint for partnerdomain.io — can you check if there's a valid _https._tcp SRV record and what it says?”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/srv/https-tcp?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically discover where a domain's HTTPS service is hosted (host, port, priority, weight) via the standard SRV DNS mechanism, without guessing subdomains or hardcoding ports. Prefer this over generic DNS A/AAAA lookups when the service uses SRV-based discovery, such as in federated protocols, SVCB/HTTPS record-adjacent setups, or microservice infrastructure. Backed by Cloudflare DoH for reliability and privacy.
Side effects
- Domain has no _https._tcp SRV record — returns empty result set
- Domain does not exist — NXDOMAIN error
- Cloudflare DoH upstream timeout or unreachable — service error
- Invalid domain name input — request validation failure
- Rate limiting or payment failure — 402 or 429 response
