## 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-a-shop-subdomain-dd3232a8
```

Example prompt: Can you check if the 'shop' subdomain exists for example.com — I want to know whether shop.example.com has an A record and what IP it points to.

## When to prefer this

Use this endpoint when you need a fast, targeted check on whether the 'shop' subdomain exists for a specific domain without performing broad subdomain enumeration. Prefer this over generic DNS lookup tools when you specifically need the A record for the shop host resolved via Cloudflare's reliable DoH infrastructure. Useful for e-commerce presence checks, domain audits, and infrastructure validation pipelines.

## Known failure modes

- Domain does not exist — returns NXDOMAIN response code with no records
- shop subdomain not configured — returns empty record set with NOERROR or NXDOMAIN
- Invalid domain format provided — may return error or empty result
- Cloudflare DoH service unavailable — request times out or returns error
- Network timeout during DoH resolution

## How this service works

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

## Output

Returns whether shop.<domain> exists as a DNS A record, the resolved IP address(es), the TTL of the record, and the DNS response code — all resolved through Cloudflare's DNS over HTTPS infrastructure.
