## 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 valheim-dns-srv-record-lookup-9ba8824b -d '<json body>'
```

Example prompt: Can you look up the Valheim SRV record for the domain mygameserver.com so I can find out what host and port the server is running on?

## When to prefer this

Use this endpoint when you specifically need to resolve the _valheim._udp SRV record for a given domain to locate a Valheim game server. Prefer the free sandbox endpoint at POST /v1/sandbox/dns-srv-valheim for testing before committing the $0.008 USDC paid call.

## Known failure modes

- No SRV record exists for _valheim._udp at the given domain — returns empty or NXDOMAIN response
- Invalid or malformed hostname input exceeding 253 characters
- Domain exists but has no Valheim-specific SRV record configured
- DNS resolution timeout or upstream DNS failure
- Hostname resolves but record type is absent

## How this service works

Call when an agent needs SRV records at _valheim._udp.{hostname} for Valheim. The caller sends the registrable domain, not the underscored name. Exact $0.008 USDC. Prefer unpaid POST /v1/sandbox/dns-srv-valheim first.

## Output

Returns the DNS SRV record details found at _valheim._udp.{hostname}, including priority, weight, port, and target hostname, allowing the caller to identify the Valheim server's network address and port.
