How this service works
Call when an agent needs SRV records at _submission._udp.{hostname} for submission over UDP. The caller sends the registrable domain, not the underscored name. Send JSON {"hostname":"example.com"}. Exact $0.001 USDC on Base. Try unpaid POST /v1/sandbox/dns-srv-submission-udp first.
Output
Returns the DNS SRV record(s) found at _submission._udp.{hostname}, including fields such as priority, weight, port, and target hostname, enabling the caller to locate the UDP submission service for the given domain.
Example use cases
Email server UDP submission discovery
“I need to find the SRV record for _submission._udp.mailprovider.com — can you look that up and tell me the target host and port for UDP submission?”
Network config for messaging service
“We're setting up a messaging client and need to know if chatservice.io has a _submission._udp SRV record — can you resolve that and give me the priority, weight, port, and target?”
Verify submission endpoint for domain
“Can you check what SRV record exists at _submission._udp for mycompany.net so I can confirm our UDP submission service is properly configured?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/dns-srv-submission-udp?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent specifically needs to resolve the _submission._udp DNS SRV record for a registrable domain. Prefer the unpaid sandbox POST /v1/sandbox/dns-srv-submission-udp first for testing; use this paid endpoint ($0.001 USDC) in production flows where a real DNS lookup is required. Choose this over generic DNS tools when the query is scoped specifically to the SRV record type for UDP submission services.
Side effects
- No SRV record exists for _submission._udp.{hostname} — returns empty or NXDOMAIN-style response
- Invalid or malformed hostname input — validation error
- Hostname exceeds 253-character limit — rejected
- DNS resolution timeout — service error
- Non-registrable domain submitted (e.g. bare TLD) — may return empty result
