How this service works
MATRIX-FED service discovery (_matrix-fed._tcp.<domain>): SRV records with priority, weight, port and target host, from Cloudflare DoH. Tells a client where the domain's matrix-fed service lives without guessing hosts. $0.01 per lookup.
Output
Returns the SRV record details for the _matrix-fed._tcp service under the queried domain, including priority, weight, port number, and target hostname, as resolved via Cloudflare's DNS over HTTPS infrastructure.
Example use cases
Matrix homeserver federation setup
“What host and port does example.com use for Matrix federation? Look up the _matrix-fed._tcp SRV record for me.”
Verify Matrix federation DNS config
“Can you check the _matrix-fed._tcp SRV record for my domain chat.mycompany.com to confirm the federation service is pointing to the right server?”
Diagnose federation connectivity issue
“I'm having trouble federating with matrix.to — can you pull the _matrix-fed._tcp SRV record so I can see where it's supposed to be routing?”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/srv/matrix-fed-tcp?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to discover the actual Matrix federation server (host and port) for a domain without manually guessing hostnames, particularly when implementing or debugging Matrix protocol federation. Prefer this over generic SRV lookups when specifically targeting the _matrix-fed._tcp service type.
Side effects
- Domain has no _matrix-fed._tcp SRV record configured — returns empty or NXDOMAIN response
- Malformed or missing domain input — returns an error
- Cloudflare DoH upstream timeout or error — transient failure
- Domain is valid but Matrix federation is not configured — no records found
