How this service works
Call when an agent needs SRV records at _autodiscover._tcp.{hostname} for Autodiscover. The caller sends the registrable domain, not the underscored name. Exact $0.01 USDC. Prefer unpaid POST /v1/sandbox/dns-srv-autodiscover first.
Output
Returns the SRV record details found at _autodiscover._tcp.{hostname}, including priority, weight, port, and the target hostname of the Autodiscover service, or an indication that no record exists.
Example use cases
Email client autoconfiguration setup
“Look up the Autodiscover SRV record for fabrikam.com — I need to find the server and port to auto-configure the mail client for this domain.”
Exchange server discovery for a domain
“Can you check if northwind.com has an _autodiscover._tcp SRV record set up? I'm trying to figure out where their Exchange Autodiscover service is running.”
Diagnosing missing Autodiscover configuration
“Query the Autodiscover SRV DNS record for tailspintoys.com and tell me what you get — I want to see if it's correctly configured or missing.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/dns-srv-autodiscover?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent specifically needs to resolve _autodiscover._tcp SRV DNS records for email client configuration or Exchange/Office 365 service discovery. Prefer the free sandbox POST /v1/sandbox/dns-srv-autodiscover endpoint first if available; use this paid endpoint ($0.01 USDC) only when the sandbox is unavailable or production accuracy is required.
Side effects
- No SRV record found for the domain — returns empty or not-found result
- Invalid or malformed hostname input — validation error
- DNS resolution timeout or network error during lookup
- Domain does not exist — NXDOMAIN response
