How this service works
Call when an agent needs SRV records at _matrix._tcp.{hostname} for Matrix. The caller sends the registrable domain, not the underscored name. Exact $0.009 USDC. Prefer unpaid POST /v1/sandbox/dns-srv-matrix first.
Output
Returns the SRV record data for _matrix._tcp.{hostname}, including fields such as priority, weight, port, and target hostname, enabling Matrix federation endpoint discovery.
Example use cases
Matrix federation server discovery
“I'm setting up a Matrix client and need to know the SRV record for _matrix._tcp on element.io — can you look that up for me?”
Verify Matrix homeserver configuration
“Can you check if synapse.example.com has a valid _matrix._tcp SRV DNS record configured so I can verify the federation is set up correctly?”
Debug Matrix federation connectivity
“I'm troubleshooting why federation isn't working with chat.mozilla.org — can you fetch the _matrix._tcp SRV record to see where it's pointing?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/dns-srv-matrix?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs to resolve Matrix federation SRV records programmatically, especially when implementing Matrix client or server federation discovery logic. Prefer the free sandbox endpoint (/v1/sandbox/dns-srv-matrix) for testing before using this paid endpoint.
Side effects
- No SRV record exists for the domain — returns empty or not-found response
- Invalid or malformed hostname input — validation error
- DNS resolution timeout or upstream failure — network error
- Domain does not support Matrix federation — no SRV entry found
