# XMPP-Client SRV Record Lookup (TCP)

> XMPP-Client SRV Record Lookup (TCP) 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).

Looks up DNS SRV records for _xmpp-client._tcp.<domain> via Cloudflare DoH, returning priority, weight, port, and target host for XMPP client service discovery.

## Facts

- Endpoint: GET https://dns.intel.rallylive.ca/dns/srv/xmpp-client-tcp?utm_source=zero.xyz
- Price: $0.01/call
- Payment: x402

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 xmpp-client-srv-record-lookup-tcp-cfb955ea
```

Example prompt: Can you find the XMPP client server details for jabber.org — I need the host, port, priority, and weight from its _xmpp-client._tcp SRV records?

## When to prefer this

Use this endpoint when you need to programmatically discover where a domain's XMPP client service is hosted without guessing hostnames, following the RFC 6120 SRV-based XMPP service discovery standard. Prefer this over manually probing common XMPP hostnames or using generic DNS tools when you specifically need _xmpp-client._tcp SRV records resolved via a reliable DoH resolver.

## Known failure modes

- Domain has no _xmpp-client._tcp SRV records configured — returns empty or NXDOMAIN response
- Invalid or malformed domain name input — returns error
- Domain exists but XMPP service is not advertised via DNS SRV — no records returned
- Cloudflare DoH upstream timeout or unavailability — transient error
- Network connectivity issues between service and Cloudflare DoH resolvers

## How this service works

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

## Output

Returns DNS SRV record data for _xmpp-client._tcp.<domain> including one or more records each containing: priority (lower = preferred), weight (load balancing), port number, and target hostname of the XMPP client service. Sourced from Cloudflare DoH.
