# COLLAB-EDGE TLS SRV Record Lookup via Cloudflare DoH

> COLLAB-EDGE TLS SRV Record Lookup via Cloudflare DoH is a paid API for AI agents from dns.intel.rallylive.ca, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-22).

Resolves _collab-edge._tls SRV DNS records for a given domain using Cloudflare DNS-over-HTTPS, returning priority, weight, port, and target host.

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 collab-edge-tls-srv-record-lookup-via-cloudflare-doh-1b84f8c9
```

Example prompt: Look up the _collab-edge._tls SRV DNS records for example.com so I can see which host and port handle its collab-edge service.

## When to prefer this

Use this endpoint when you need to perform SRV-based service discovery specifically for the _collab-edge._tls service (used by Cisco/Webex collaboration infrastructure) for a given domain, and you want results from Cloudflare's DoH resolver rather than the system default resolver. Prefer over general DNS tools when you need a reliable, filtered, privacy-preserving lookup with structured output including priority/weight/port/host fields.

## Known failure modes

- Domain has no _collab-edge._tls SRV record configured (NXDOMAIN response)
- Domain does not exist (NXDOMAIN)
- Cloudflare DoH upstream timeout or error
- Missing or invalid domain input parameter
- Rate limiting or payment failure for the $0.01 per-call fee

## How this service works

COLLAB-EDGE service discovery (_collab-edge._tls.<domain>): SRV records with priority, weight, port and target host, from Cloudflare DoH. Tells a client where the domain's collab-edge service lives without guessing hosts. $0.01 per lookup.

## Output

Returns SRV record data for _collab-edge._tls.<domain> including one or more records each with priority, weight, port, and target hostname, along with the TTL and DNS response code (e.g. NOERROR or NXDOMAIN). Sourced from Cloudflare DNS-over-HTTPS.
