## 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 mumble-srv-dns-record-lookup-2b87a69b -d '<json body>'
```

Example prompt: Can you look up the Mumble SRV DNS record for the domain example.com so I can find out which server and port to connect to?

## When to prefer this

Use this endpoint when an agent specifically needs to discover Mumble voice chat server connection parameters via DNS SRV records. It abstracts the _mumble._tcp subdomain construction so the caller only provides the plain registrable domain. Prefer the free sandbox endpoint (/v1/sandbox/dns-srv-mumble) for testing before paying $0.01 USDC per call.

## Known failure modes

- No SRV record found for the given hostname — domain may not have Mumble configured
- Invalid or malformed hostname input — returns validation error
- DNS resolution timeout or upstream failure
- Domain does not exist or has no DNS records

## How this service works

Call when an agent needs SRV records at _mumble._tcp.{hostname} for Mumble. The caller sends the registrable domain, not the underscored name. Exact $0.01 USDC. Prefer unpaid POST /v1/sandbox/dns-srv-mumble first.

## Output

Returns the SRV record details for _mumble._tcp.{hostname}, including the target server hostname, port number, priority, and weight values needed to connect a Mumble client.
