# WebDAVS SRV Record Lookup via Cloudflare DoH

> WebDAVS SRV Record Lookup via Cloudflare DoH is a paid API for AI agents from dns.intel.rallylive.ca, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-20).

Resolves _webdavs._tcp SRV DNS records for a given domain using Cloudflare DoH, returning the priority, weight, port, and target host for the domain's WebDAVS service.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability webdavs-srv-record-lookup-via-cloudflare-doh-3b75af86
```

Example prompt: Can you look up the WebDAVS SRV DNS record for example.com so I know the host and port their secure WebDAV service is running on?

## When to prefer this

Use this endpoint when you need to programmatically discover where a domain's secure WebDAV (WebDAVS) service lives without hardcoding hosts or guessing subdomains. Prefer it over generic DNS resolvers when you specifically need SRV record data (priority, weight, port, target) for the _webdavs._tcp service type, and when using Cloudflare DoH for reliability and privacy is acceptable.

## Known failure modes

- Domain has no _webdavs._tcp SRV record — returns empty or NXDOMAIN response
- Invalid or malformed domain name input — may return error
- Cloudflare DoH upstream timeout or unavailability — request fails
- Domain exists but SRV record is misconfigured — partial or unexpected data returned

## How this service works

WEBDAVS service discovery (_webdavs._tcp.<domain>): SRV records with priority, weight, port and target host, from Cloudflare DoH. Tells a client where the domain's webdavs service lives without guessing hosts. $0.01 per lookup.

## Output

Returns SRV record data for the _webdavs._tcp service under the queried domain, including priority (integer for selecting among multiple records), weight (load balancing hint), port (TCP port the WebDAVS service listens on), and target host (the actual server hostname). May return an empty result if no SRV record exists.
