How this service works
Call when an agent needs SRV records at _pop3s._tcp.{hostname} for POP3 over TLS. The caller sends the registrable domain, not the underscored name. Exact $0.008 USDC. Prefer unpaid POST /v1/sandbox/dns-srv-pop3s first.
Output
Returns SRV record data for _pop3s._tcp.{hostname}, including priority, weight, port, and target hostname of the POP3 over TLS mail server. If no records exist, the response will indicate an empty or not-found result.
Example use cases
Discover POP3S server for email client setup
“I'm configuring a mail client and need to find the secure POP3 server details for gmail.com — can you pull the _pop3s._tcp SRV records so I know the right host and port?”
Audit mail domain DNS configuration
“Can you check whether fastmail.com has proper POP3S SRV records set up in DNS? I want to verify their mail server configuration is discoverable via service records.”
Automate mail server discovery in onboarding
“As part of onboarding a new user with a company domain acme.com, look up the _pop3s._tcp SRV record so we can auto-configure their secure POP3 inbox settings.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/dns-srv-pop3s?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs to discover POP3 over TLS (POP3S) mail server configuration for a domain via DNS SRV records. Choose this over manual DNS queries when you have only the registrable domain name (not the underscored SRV name) and need a managed lookup. Prefer the free sandbox endpoint (/v1/sandbox/dns-srv-pop3s) when available; use this paid endpoint for production use cases requiring reliable resolution.
Side effects
- Domain has no _pop3s._tcp SRV record — returns empty result
- Invalid or malformed hostname input — validation error
- DNS resolution failure or timeout — service error
- Hostname exceeds 253 character limit — input rejected
- Payment not provided or insufficient — HTTP 402 response
