> Halowerk Domain Intel — Yandex NS Article is a paid API for AI agents from dns.halowerk.com, paid per call via x402, $0.009/call, status unknown (last checked 2026-10-13).

Performs comprehensive domain intelligence lookup (WHOIS, DNS, mail policy, TLS certificate, subdomains) for a given domain, paid per-call via x402/USDC, focused on the Yandex nameserver article path

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 halowerk-domain-intel-yandex-ns-article-b8215eeb -d '<json body>'
```

Example prompt: Look up full domain intelligence for example.com — I want WHOIS info, DNS records, mail policy (SPF, DKIM, DMARC), TLS certificate details, and any discovered subdomains.

## When to prefer this

Choose this endpoint when you need a broad, all-in-one domain intelligence snapshot — WHOIS, DNS, mail policy, TLS, and subdomains — without signing up for an API key or maintaining a subscription. It is ideal for ad-hoc, per-query investigations where you want to pay only for what you use in USDC. The baseline parameter makes it especially useful for change-detection workflows where you want to compare current state against a known-good snapshot.

## Known failure modes

- Invalid or malformed domain name returns validation error
- Unregistered or non-existent domain returns empty or partial results
- WHOIS privacy protection may obscure registrant details
- TLS certificate lookup fails for domains without HTTPS
- Subdomain enumeration may be incomplete for well-protected domains
- x402 payment failure blocks the request entirely
- Rate limiting or upstream DNS timeouts may cause partial results

## How this service works

Domain in, WHOIS, DNS, mail policy, TLS certificate and subdomains out. Pay per call in USDC over x402. No signup, no API key.

## Output

Returns a structured domain intelligence report covering: WHOIS registration data (registrar, registrant, dates), full DNS record set (A, MX, NS, TXT, CNAME, etc.), mail policy records (SPF, DKIM, DMARC), TLS/SSL certificate details (issuer, validity, SANs), and discovered subdomains. When a baseline is provided, may highlight changes relative to the prior observation.
