# Halowerk Domain Intel — MX / Zoho Mail Article Endpoint

> Halowerk Domain Intel — MX / Zoho Mail Article Endpoint is a paid API for AI agents from dns.halowerk.com, paid per call via x402, $0.009/call, status unknown (last checked 2026-10-12).

Accepts a domain name and optional MX baseline, then returns WHOIS, DNS, mail policy (MX records), TLS certificate, and subdomain intelligence for that domain — paid per call via x402/USDC.

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-mx-zoho-mail-article-endpoint-e964d0c6 -d '<json body>'
```

Example prompt: Pull the full domain intel for acmecorp.com — I need its WHOIS, DNS records, MX mail servers, TLS certificate, and subdomains, and compare the MX records against this baseline: mail.acmecorp.com at priority 10 observed on 2024-01-15.

## When to prefer this

Choose this endpoint when you need a single pay-per-call, no-signup lookup of comprehensive domain intelligence — especially WHOIS, DNS, MX mail configuration, TLS certificates, and subdomains — without committing to a subscription or API key. It is particularly suited for agents that need to verify or audit mail routing (including Zoho Mail setups) and can optionally diff results against a stored MX baseline. Prefer alternatives if you need bulk domain lookups, real-time streaming, or a free tier.

## Known failure modes

- Invalid or non-existent domain returns an error or empty record sets
- Malformed baseline object (missing required fields) causes a 400/validation error
- Payment failure or insufficient USDC balance causes x402 payment-required rejection
- Domain too long (>253 chars) rejected by schema validation
- Network timeout if the target domain's authoritative DNS is slow to respond
- MX record count exceeding 50 items truncated per schema limit

## 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 payload containing WHOIS registration data, full DNS record set, MX records with priorities and exchange hosts, mail policy details, TLS certificate information (issuer, expiry, SANs), and discovered subdomains for the queried domain. If a baseline is provided, the response may highlight deviations from the prior observed state.
