How this service works
Call when an agent needs SRV records at _caldav._tcp.{hostname} for CalDAV. The caller sends the registrable domain, not the underscored name. Exact $0.002 USDC. Prefer unpaid POST /v1/sandbox/dns-srv-caldav first.
Output
Returns the SRV record fields from _caldav._tcp.{hostname}, including the target CalDAV server hostname, port number, priority, and weight, enabling clients to locate and connect to the correct CalDAV service.
Example use cases
Calendar app auto-configuration
“I'm setting up a calendar client for acme.com — can you fetch the CalDAV SRV record for acme.com so I know which server and port to connect to?”
Diagnose CalDAV discovery failure
“My calendar app can't find the CalDAV server for mycompany.org — can you check the _caldav._tcp SRV DNS record for mycompany.org and tell me what it says?”
Verify CalDAV server deployment
“We just set up CalDAV for ourschool.edu — can you query the SRV record for ourschool.edu to confirm the DNS entry is pointing to the right server and port?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/dns-srv-caldav?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs to programmatically discover a CalDAV server for a given domain via DNS SRV records, especially during calendar client auto-configuration or service validation workflows. It is purpose-built for the CalDAV SRV lookup pattern, avoiding the need for general DNS libraries or direct DNS queries.
Side effects
- No SRV record exists for the given hostname (NXDOMAIN or empty answer)
- Hostname is malformed or exceeds 253 characters
- DNS resolution timeout or upstream DNS failure
- Domain exists but has no _caldav._tcp SRV record configured
