How this service works
Call when an agent needs SRV records at _pop3._tcp.{hostname} for POP3. The caller sends the registrable domain, not the underscored name. Exact $0.008 USDC. Prefer unpaid POST /v1/sandbox/dns-srv-pop3 first.
Output
Returns the SRV record data for _pop3._tcp.{hostname}, including fields such as priority, weight, port, and target hostname of the POP3 mail server, as resolved from DNS.
Example use cases
Email client auto-configuration
“I'm setting up an email client for someone on acmecorp.com — can you look up the POP3 SRV records so I know which server and port to connect to?”
Mail infrastructure audit
“We're auditing the mail infrastructure for contoso.org — pull the _pop3._tcp SRV records so we can verify the correct POP3 server is advertised in DNS.”
Automated mailbox provisioning
“Before provisioning a new mailbox on fabrikam.net, check what POP3 SRV records are published in DNS so the system knows where to route incoming mail retrieval.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/dns-srv-pop3?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs to programmatically discover the POP3 mail server address and port for a domain via DNS SRV records, particularly during email client auto-configuration, mail infrastructure auditing, or automated mailbox provisioning workflows. Prefer the free sandbox endpoint (/v1/sandbox/dns-srv-pop3) for testing before using this paid endpoint.
Side effects
- Domain has no _pop3._tcp SRV record — returns empty or not-found response
- Invalid or malformed hostname input — returns validation error
- DNS resolution timeout or upstream DNS failure — returns error
- Non-existent domain — DNS NXDOMAIN response
