How this service works
Call when an agent needs SRV records at _smb._tcp.{hostname} for SMB. The caller sends the registrable domain, not the underscored name. Exact $0.005 USDC. Prefer unpaid POST /v1/sandbox/dns-srv-smb first.
Output
Returns SRV record data for _smb._tcp.{hostname}, including the priority, weight, port, and target hostname of the SMB server(s) registered in DNS for that domain.
Example use cases
Discover SMB server for enterprise domain
“Look up the SMB SRV DNS records for contoso.com — I need to find out what server and port handle SMB file sharing for that domain.”
Verify SMB service discovery configuration
“Can you check if corp.acme.org has _smb._tcp SRV records set up in DNS? I want to confirm the SMB service discovery is properly configured.”
Automate SMB endpoint resolution
“Resolve the SMB SRV records for fabrikam.net so my script can automatically connect to the right SMB server without hardcoding an IP address.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/dns-srv-smb?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically discover the SMB server location for a domain via DNS SRV records (_smb._tcp). Prefer the unpaid sandbox POST /v1/sandbox/dns-srv-smb for testing. Choose this paid endpoint for production lookups where reliable DNS resolution of SMB service endpoints is required.
Side effects
- Domain has no _smb._tcp SRV records configured — returns empty or NXDOMAIN result
- Invalid or malformed hostname input — returns validation error
- DNS resolution timeout or upstream DNS failure — returns error response
- Payment of $0.005 USDC not provided or rejected — returns 402 Payment Required
