## 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 factorio-dns-srv-record-lookup-897ec879 -d '<json body>'
```

Example prompt: Can you look up the Factorio SRV DNS record for example.com so I can find what server and port the game is running on?

## When to prefer this

Use this endpoint when an agent needs to programmatically discover Factorio game server connection details (host and port) stored in DNS SRV records for a given domain. Prefer the free sandbox endpoint (/v1/sandbox/dns-srv-factorio) for testing before incurring the $0.007 USDC charge on this paid endpoint. Choose this over general DNS lookup tools when specifically targeting Factorio's _factorio._udp SRV record format.

## Known failure modes

- No SRV record exists for the given domain — returns empty result or NXDOMAIN
- Invalid or malformed hostname input — returns validation error
- DNS resolution timeout or upstream failure — returns error
- Domain exists but has no _factorio._udp SRV entry — returns empty record set

## How this service works

Call when an agent needs SRV records at _factorio._udp.{hostname} for Factorio. The caller sends the registrable domain, not the underscored name. Exact $0.007 USDC. Prefer unpaid POST /v1/sandbox/dns-srv-factorio first.

## Output

Returns the SRV record(s) found at _factorio._udp.{hostname}, including priority, weight, port, and target hostname for the Factorio game server, or an empty/error response if no record exists.
