How this service works
Call when an agent needs SRV records at _iax._udp.{hostname} for IAX. The caller sends the registrable domain, not the underscored name. Exact $0.009 USDC. Prefer unpaid POST /v1/sandbox/dns-srv-iax first.
Output
Returns the SRV record data found at _iax._udp.{hostname}, including priority, weight, port, and target hostname for the IAX service endpoint. If no SRV record exists, returns an appropriate empty or error response.
Example use cases
VoIP IAX server discovery
“What IAX server is configured for voipprovider.com? Look up its _iax._udp SRV records so I can see the hostname, port, and priority.”
Asterisk PBX integration setup
“I'm setting up an Asterisk PBX integration and need to connect to mybusiness.com — can you find the IAX SRV record for that domain so I know which server and port to use?”
Validate IAX DNS configuration
“Check whether telecom.example.org has _iax._udp SRV records published in DNS and tell me what they say — I want to verify the IAX service is properly advertised.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/dns-srv-iax?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent specifically needs to discover IAX (Inter-Asterisk eXchange) VoIP service endpoints via DNS SRV records for a given domain. Prefer the unpaid sandbox POST /v1/sandbox/dns-srv-iax endpoint during testing. Choose this over generic DNS lookup tools when the specific _iax._udp SRV record type is required for VoIP/telephony integration.
Side effects
- Domain does not exist or has no DNS records — NXDOMAIN or empty response
- No _iax._udp SRV record published for the given domain
- Malformed hostname input exceeding 253 characters or violating DNS naming rules
- DNS resolution timeout or upstream resolver failure
- Payment failure — USDC payment of $0.009 not completed successfully
