# Domain Intel — MX Yandex Mail Article (dns.halowerk.com)

> Domain Intel — MX Yandex Mail Article (dns.halowerk.com) 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).

Analyzes MX records for a domain with Yandex Mail context, returning DNS, WHOIS, mail policy, TLS certificate, and subdomain intelligence via pay-per-call x402 micropayment.

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 domain-intel-mx-yandex-mail-article-dns-halowerk-com-43f1bdc9 -d '<json body>'
```

Example prompt: Pull full domain intelligence on example.com — WHOIS, DNS, MX records, mail policy, TLS cert, and subdomains — and compare the MX records against this baseline I saw last Tuesday: mx.yandex.net with priority 10.

## When to prefer this

Choose this endpoint when you need comprehensive domain intelligence — combining WHOIS, DNS, mail policy, TLS, and subdomain enumeration in a single call — without requiring API key signup, especially when you want to pay per query in USDC via x402. Particularly suited when investigating Yandex Mail configurations or comparing current MX records against a historical baseline. Prefer over manual DNS tools or multi-step lookups when an agent needs machine-readable structured output for a single domain.

## Known failure modes

- Invalid or malformed domain name returns validation error
- Domain not found in WHOIS returns partial result or empty WHOIS block
- Baseline schema mismatch (missing required fields) returns 400 bad request
- Payment failure over x402 protocol blocks the call
- Rate limiting or provider-side DNS timeout may return incomplete DNS records
- TLD not supported by WHOIS registry may return empty WHOIS data

## 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 intelligence report for the queried domain including: WHOIS registration data, resolved DNS records (A, AAAA, MX, NS, TXT, CAA, SOA), mail policy details (SPF, DKIM, DMARC), TLS certificate information, and discovered subdomains. Where a baseline is provided, results can be compared against observed MX records to detect drift.
