How this service works
Call when an agent needs SRV records at _vlmcs._tcp.{hostname} for KMS. The caller sends the registrable domain, not the underscored name. Send JSON {"hostname":"example.com"}. Exact $0.006 USDC on Base. Try unpaid POST /v1/sandbox/dns-srv-vlmcs first.
Output
Returns the SRV record details found at _vlmcs._tcp.{hostname}, including the target KMS server hostname, port number, priority, and weight values that DNS has published for that domain's Key Management Service.
Example use cases
Verify KMS server for enterprise domain
“Can you find the KMS server SRV record for microsoft.com? I need to know what host and port are set up for _vlmcs._tcp so I can check if volume licensing is configured correctly.”
Diagnose Windows activation failure
“Our machines at acmecorp.com are failing to auto-activate Windows. Can you look up the _vlmcs._tcp SRV record for acmecorp.com to see if the KMS server DNS entry exists and what it points to?”
Audit KMS DNS configuration
“I'm auditing our DNS setup — can you resolve the VLMCS SRV record for example.org so I can confirm the KMS hostname, port, priority and weight are all set correctly?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/dns-srv-vlmcs?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs to programmatically discover or audit KMS (Key Management Service) server configuration for a domain via its _vlmcs._tcp SRV DNS record, without needing to query DNS directly. Prefer the free sandbox endpoint POST /v1/sandbox/dns-srv-vlmcs when available to avoid the $0.006 USDC charge.
Side effects
- Domain not found or no SRV record exists at _vlmcs._tcp.{hostname} — returns empty or error response
- Invalid or malformed hostname input — validation error
- DNS resolution timeout or upstream DNS failure
- Hostname exceeds 253 character limit
