How this service works
Call when an agent needs SRV records at _presence._tcp.{hostname} for XMPP presence. The caller sends the registrable domain, not the underscored name. Exact $0.005 USDC. Prefer unpaid POST /v1/sandbox/dns-srv-presence first.
Output
Returns the SRV record entries found at _presence._tcp.{hostname}, including fields such as priority, weight, port, and target hostname for each record. If no records exist, returns an empty result or appropriate indicator.
Example use cases
XMPP chat client configuration
“I'm setting up an XMPP client for jabber.org and need the SRV records for _presence._tcp to know which server and port to connect to — can you look that up?”
Verify XMPP presence deployment
“Can you check whether syntexa.ch has any _presence._tcp SRV records configured? I want to confirm our XMPP presence service is properly published in DNS.”
Troubleshoot XMPP federation issues
“We're having trouble federating XMPP presence with partner.example.com — can you pull the _presence._tcp SRV records for that domain so I can see what they have configured?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/dns-srv-presence?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need to resolve _presence._tcp SRV records for XMPP presence service discovery and are willing to pay $0.005 USDC per lookup. If a free sandbox alternative at POST /v1/sandbox/dns-srv-presence is available, prefer that first. Choose this over generic DNS lookup tools when you need XMPP-specific presence record resolution without constructing the underscored service name yourself.
Side effects
- Domain not found or no DNS records exist — returns empty or error response
- Invalid hostname format (too long, empty, or malformed) — input validation error
- DNS resolution timeout — transient network failure
- Domain exists but has no _presence._tcp SRV records — empty result set
