Example prompt: Can you check if stripe.com has its DNS hosted on AWS Route 53 — I want to know whether it uses Route 53 nameservers and which ones matched?

## When to prefer this

Use this endpoint when you need a quick, cheap ($0.01) programmatic check of whether a specific domain is using AWS Route 53 as its DNS host — ideal for sales prospecting pipelines, infrastructure audits, migration planning, or security vendor-detection workflows where you need NS-level evidence, not just a guess.

## Known failure modes

- Domain does not exist or has no NS records — returns no match with empty nameserver list
- Cloudflare DoH lookup failure — network or upstream DNS resolution error
- Invalid or malformed domain input — may return error or empty result
- Domain uses custom/vanity nameservers that alias Route 53 — may not be detected

## How this service works

Is the domain's DNS hosted by aws route 53? Looks up the NS records (Cloudflare DoH) and matches them against aws-route-53's nameserver patterns, returning yes/no, the nameservers and which ones matched. Vendor detection for sales, migration and security work. $0.01 per lookup.

## Output

Returns a yes/no boolean indicating whether the domain's DNS is hosted on AWS Route 53, the full list of NS records retrieved via Cloudflare DoH, and a subset list of which nameservers matched Route 53 patterns.
