## 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-store-subdomain-d381eb22
```

Example prompt: Can you check whether store.shopify.com has a CNAME record set up — I want to know if it exists, what it points to, and the TTL?

## When to prefer this

Choose this endpoint when you need a quick, single-shot existence check for the store subdomain CNAME record on a specific domain, without enumerating all subdomains. It's best when you already know you want the store host specifically and need CNAME record data (not A or AAAA), and you want results from Cloudflare's globally distributed DoH resolver for reliability and privacy.

## Known failure modes

- Domain does not exist — returns NXDOMAIN or no-record response
- store subdomain has no CNAME record (may have A/AAAA instead)
- Cloudflare DoH service temporarily unavailable
- Invalid or malformed domain input causes lookup failure
- Network timeout reaching Cloudflare DoH resolver

## How this service works

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

## Output

Returns whether the CNAME record for store.<domain> exists, the record value(s) it contains (i.e. the canonical hostname it points to), and the TTL in seconds, as resolved via Cloudflare DNS over HTTPS.
