# dns-cname-shop-subdomain

> dns-cname-shop-subdomain is a paid API for AI agents from dns.intel.rallylive.ca, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-21).

Looks up the CNAME record for the 'shop' subdomain of a given domain using Cloudflare DNS over HTTPS, reporting existence, records, and TTL.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-shop-subdomain-c952ac23
```

Example prompt: Can you check whether shop.acme.com exists as a CNAME — just look up the shop subdomain under acme.com and tell me what it resolves to and the TTL?

## When to prefer this

Use this endpoint when you need a quick, targeted check for the 'shop' subdomain specifically on a given domain without performing broad subdomain enumeration. Ideal for e-commerce platform detection, pre-launch DNS validation, or competitive research when you want to know if a shop subdomain is CNAME'd to a third-party service. Prefer this over generic DNS tools when you want a low-cost ($0.01), single-purpose check via Cloudflare DoH for reliability.

## Known failure modes

- Domain does not have a shop subdomain — returns not-found or NXDOMAIN response
- Invalid or malformed domain input — may return an error or empty result
- Cloudflare DoH service unavailable — lookup fails with a connectivity error
- Domain exists but shop subdomain has no CNAME (only A/AAAA records) — returns no CNAME data

## How this service works

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

## Output

Returns whether the shop.<domain> CNAME record exists, the actual CNAME record value(s), the TTL in seconds, and the DNS response code from Cloudflare DoH.
