How this service works
MATRIX service discovery (_matrix._tcp.<domain>): SRV records with priority, weight, port and target host, from Cloudflare DoH. Tells a client where the domain's matrix service lives without guessing hosts. $0.01 per lookup.
Output
Returns SRV record data for _matrix._tcp.<domain> including priority, weight, port number, and target hostname, sourced from Cloudflare DoH. Enables a Matrix client or federation service to directly connect to the correct homeserver without guessing.
Example use cases
Matrix federation homeserver discovery
“I'm setting up Matrix federation and need to connect to example.com — can you look up their _matrix._tcp SRV record so I know the right host and port to use?”
Verifying Matrix deployment configuration
“We just deployed a Matrix homeserver for acme-corp.com — can you pull the _matrix._tcp SRV record for that domain to confirm it's pointing to the right host and port?”
Debugging Matrix server connection failure
“My Matrix client can't connect to a federated server on mozilla.org — can you resolve the _matrix._tcp SRV record for mozilla.org so I can see what host and port it's supposed to be using?”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/srv/matrix-tcp?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to discover a Matrix homeserver's actual host and port for a given domain via the standard SRV record mechanism, especially for federation or client configuration. Prefer this over guessing default ports or using A/AAAA records directly, as SRV records carry authoritative priority, weight, and port data.
Side effects
- Domain has no _matrix._tcp SRV record — returns empty or NXDOMAIN response
- Domain does not exist — DNS resolution fails entirely
- Cloudflare DoH is temporarily unavailable — request times out
- Malformed domain input — query rejected or returns error
- Payment of $0.01 USDC not fulfilled — request blocked by x402 paywall
