## 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 is-dns-hosted-by-yandex-14c0f5de
```

Example prompt: Can you check if example.com has its DNS hosted by Yandex — I need to know if their nameservers match Yandex's patterns?

## When to prefer this

Use this endpoint when you need to definitively determine if a specific domain's authoritative DNS is managed by Yandex, particularly for sales intelligence, pre-migration audits, or security investigations targeting Yandex infrastructure. It is purpose-built for Yandex detection with pattern matching, unlike generic NS lookup tools that require manual interpretation.

## Known failure modes

- Domain does not exist or has no NS records — returns empty nameservers and no match
- Cloudflare DoH lookup fails due to network issues — lookup error returned
- Invalid or malformed domain name input — request fails validation
- Domain has NS records but none match Yandex patterns — returns hosted=no with nameservers listed

## How this service works

Is the domain's DNS hosted by yandex? Looks up the NS records (Cloudflare DoH) and matches them against yandex'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 indicator of whether the domain's DNS is hosted by Yandex, the full list of NS records retrieved via Cloudflare DoH, and which specific nameservers matched Yandex's known nameserver patterns.
