## 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-record-lookup-for-remote-domain-subdomain-via-cloudflare-doh-87360cc5
```

Example prompt: Can you check if there's an A record for the 'remote' subdomain of acme.com — I want to know if it exists, what IP it points to, and its TTL?

## When to prefer this

Use this endpoint when you need a quick, targeted existence and resolution check for the 'remote' subdomain of a specific domain without doing full subdomain enumeration. Ideal for infrastructure audits, security checks, or pre-deployment verification where Cloudflare DoH accuracy is preferred over other resolvers.

## Known failure modes

- Domain does not exist — returns NXDOMAIN response code with no records
- remote subdomain not configured — NXDOMAIN or empty answer section
- Invalid domain name format — may return error or empty result
- Cloudflare DoH service temporarily unavailable — lookup fails
- Network timeout reaching Cloudflare resolver

## How this service works

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

## Output

Returns whether the 'remote' subdomain exists under the given domain, its DNS A record(s) (IP addresses), the TTL of those records, and the DNS response code (e.g. NOERROR or NXDOMAIN) as answered by Cloudflare DoH.
