## 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 dns-cname-lookup-for-video-subdomain-8d6d28cd
```

Example prompt: Can you check if video.rallylive.ca has a CNAME record and tell me what host it points to and its TTL?

## When to prefer this

Use this endpoint when you need a quick, cheap existence check for the video.<domain> CNAME specifically, without enumerating all subdomains. Prefer it over full DNS enumeration tools when you only care about this one common host, or when you want to verify video hosting configuration for a known domain.

## Known failure modes

- Domain does not have a video subdomain CNAME record — returns not found or empty result
- Invalid or malformed domain name input — may return an error or empty response
- Cloudflare DoH upstream timeout or unavailability — may return a lookup failure
- Domain exists but video subdomain has an A/AAAA record instead of CNAME — CNAME query returns no results

## How this service works

CNAME record of video.<domain>: looks up the video host under the domain you give (CNAME via Cloudflare DoH) and reports whether it exists, its records and TTL. Quick existence check for common hosts like video without enumerating subdomains. $0.01 per lookup.

## Output

Returns whether the video.<domain> CNAME record exists, the resolved canonical hostname(s) it points to, and the TTL value of the record. If no record is found, reports non-existence.
