## 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-redis-subdomain-44609fdb
```

Example prompt: Can you check if there's a redis CNAME DNS record configured under example.com — I want to know if it exists, what it points to, and the TTL?

## When to prefer this

Use this endpoint when you need a fast, targeted existence check for a redis subdomain CNAME record on a specific domain without performing broad subdomain enumeration. Ideal for infrastructure audits, passive DNS recon, pre-migration checks, or domain intelligence enrichment where you only care about the redis host specifically and want a single, inexpensive lookup.

## Known failure modes

- Domain does not exist — returns NXDOMAIN or empty records
- redis subdomain has no CNAME record — returns empty or negative response
- Cloudflare DoH service unavailable — request fails or times out
- Invalid domain input — malformed domain causes query failure
- Domain has A record but no CNAME for redis — response reflects record type mismatch

## How this service works

CNAME record of redis.<domain>: looks up the redis 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 redis without enumerating subdomains. $0.01 per lookup.

## Output

Returns whether a CNAME record exists for redis.<domain>, including the full CNAME target hostname, the TTL value, and the DNS response code — allowing quick verification of whether a redis host is configured under the queried domain.
