## 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 jabber-srv-dns-lookup-via-cloudflare-doh-25b4777c
```

Example prompt: What are the _jabber._tcp SRV records for example.com — I need the priority, weight, port, and target host so I can configure my XMPP client to connect to their Jabber service.

## When to prefer this

Choose this endpoint when you need to programmatically discover where a domain's XMPP/Jabber service lives — especially for configuring XMPP clients, debugging federation issues, or validating Jabber service deployment. It queries specifically the _jabber._tcp SRV record via Cloudflare DoH, which is authoritative and privacy-preserving, as opposed to generic SRV or MX lookups.

## Known failure modes

- NXDOMAIN if the domain has no _jabber._tcp SRV record configured
- Empty answer if the domain exists but has no Jabber SRV record
- Timeout or error if Cloudflare DoH is unreachable
- Invalid domain input causing a DNS query error

## How this service works

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

## Output

Returns the SRV DNS records for _jabber._tcp.<domain> as answered by Cloudflare DoH, including each record's priority, weight, port, and target hostname, along with the TTL and DNS response code (e.g. NOERROR or NXDOMAIN).
