How this service works
Call when an agent needs SRV records at _kerberos._tcp.{hostname} for Kerberos. The caller sends the registrable domain, not the underscored name. Exact $0.002 USDC. Prefer unpaid POST /v1/sandbox/dns-srv-kerberos first.
Output
Returns the SRV records found at _kerberos._tcp.<hostname>, including priority, weight, port, and target hostname for each Kerberos server entry. An empty records array is returned (and billed) if no records exist.
Example use cases
Discover enterprise Kerberos KDC servers
“Can you look up the Kerberos SRV records for corp.acme.com? I need to find out which Key Distribution Center servers the company has registered in DNS.”
Validate Kerberos DNS configuration
“Check if university.edu has any _kerberos._tcp SRV records configured — I'm trying to confirm their Kerberos realm is properly advertised in DNS.”
Network authentication troubleshooting
“I'm having Kerberos auth issues connecting to services on contoso.com — can you pull the SRV records for that domain so I can see what KDC hosts and ports are listed?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/dns-srv-kerberos?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs to programmatically discover Kerberos Key Distribution Center (KDC) servers for a domain via DNS SRV records, particularly in enterprise authentication workflows, network configuration checks, or Kerberos realm discovery. Prefer the free sandbox endpoint (unpaid POST /v1/sandbox/dns-srv-kerberos) for testing. Choose this paid endpoint for production queries where a real authoritative DNS answer is required.
Side effects
- No SRV records found — returns empty records array but still charges $0.002
- Invalid or malformed hostname input — likely validation error
- DNS resolution timeout or upstream failure — service error response
- Hostname exceeds 253 character limit — schema validation rejection
- Payment failure — x402 payment required before response is delivered
