How this service works
Call when an agent needs SRV records at _dns-sd._udp.{hostname} for DNS-SD. The caller sends the registrable domain, not the underscored name. Exact $0.01 USDC. Prefer unpaid POST /v1/sandbox/dns-srv-dns-sd first.
Output
Returns the SRV records found at _dns-sd._udp.{hostname}, including priority, weight, port, and target host for each service entry discovered via DNS-SD under the given registrable domain.
Example use cases
Service discovery for home network
“Look up the DNS-SD SRV records for local.example.net — I want to see what services are being announced on that domain.”
Verify DNS-SD setup for a domain
“Can you check the _dns-sd._udp SRV records for mycompany.com so I can confirm our DNS-based service discovery is configured correctly?”
Audit advertised services on a domain
“Fetch the DNS-SD SRV records for acmecorp.io — I need to audit what services are being published via DNS service discovery on that domain.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/dns-srv-dns-sd?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent specifically needs DNS-SD SRV records (at _dns-sd._udp.{hostname}) for a registrable domain, such as auditing service discovery configurations or resolving what network services a domain advertises. Prefer the free POST /v1/sandbox/dns-srv-dns-sd endpoint during testing. Choose this over generic DNS lookup tools when you need the DNS-SD-specific underscore-prefixed SRV path resolved automatically from a plain registrable domain name.
Side effects
- Domain not found or no SRV records exist at _dns-sd._udp.{hostname} — returns empty or error response
- Invalid or malformed hostname input (exceeds 253 chars or empty) — returns validation error
- Network timeout when querying authoritative DNS servers
- Non-registrable or private/internal domain name supplied — may return no results
- Payment failure for the $0.01 USDC charge — request rejected before DNS lookup
