How this service works
CALDAVS service discovery (_caldavs._tcp.<domain>): SRV records with priority, weight, port and target host, from Cloudflare DoH. Tells a client where the domain's caldavs service lives without guessing hosts. $0.01 per lookup.
Output
Returns the SRV record set for _caldavs._tcp.<domain> including priority, weight, port number, and target hostname for each record, sourced from Cloudflare's DNS over HTTPS resolver. If no SRV record exists, returns an empty or error result.
Example use cases
Calendar client auto-configuration
“I'm setting up a CalDAV client for contoso.com — can you find the _caldavs._tcp SRV record so I know which host and port to point it at?”
Verifying CalDAVS service deployment
“We just deployed our secure CalDAV server — can you check the _caldavs._tcp SRV record for mycompany.org and confirm the host, port, priority, and weight are set correctly?”
Diagnosing calendar sync failures
“Our users can't sync their calendars — can you do a _caldavs._tcp SRV lookup on ourworkplace.com to see if the service discovery record is present and pointing somewhere?”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/srv/caldavs-tcp?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically discover where a domain's secure CalDAV (CalDAVS) server lives without hardcoding hostnames, especially for calendar client auto-configuration, infrastructure verification, or diagnosing calendar sync issues. Prefer this over generic DNS resolvers when you specifically need the SRV record for the caldavs-tcp service type and want a paid, reliable Cloudflare DoH-backed result.
Side effects
- Domain has no _caldavs._tcp SRV record published — returns empty result
- Invalid or malformed domain name input — returns error
- DNS resolution failure at Cloudflare DoH — returns upstream error
- Payment not processed (x402) — request rejected before DNS lookup
