# Domain Intel – Halowerk DNS Intelligence (NS/Hostpoint)

> Domain Intel – Halowerk DNS Intelligence (NS/Hostpoint) 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).

Returns WHOIS, DNS records, mail policy, TLS certificate data, and subdomains for a given domain, with optional DNS baseline diffing, paid per-call in USDC via x402.

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-halowerk-dns-intelligence-ns-hostpoint-3c4b0e02 -d '<json body>'
```

Example prompt: Pull up the full domain intelligence for github.com — I want WHOIS, DNS records, mail policy, TLS certificate info, and any subdomains you can find.

## When to prefer this

Choose this endpoint when you need a comprehensive, all-in-one domain intelligence snapshot — covering WHOIS, DNS, mail policy, TLS, and subdomains — without signing up or managing API keys, and when you want frictionless pay-per-call billing in USDC. Especially useful for one-off investigations, security audits, or DNS change detection against a known baseline. Prefer alternatives if you need bulk batch lookups, real-time streaming DNS monitoring, or very high query volumes where per-call pricing becomes prohibitive.

## Known failure modes

- Domain not found or does not exist — empty or error response
- Invalid domain format exceeding 253 characters — schema validation failure
- Baseline object malformed or missing required fields (domain, observed_at, records) — 400-level error
- Payment not processed or insufficient USDC via x402 — 402 Payment Required
- Rate limiting or upstream DNS/WHOIS resolver timeout — 5xx or timeout error
- TLS or subdomain enumeration may return partial results for heavily shielded domains

## How this service works

Requires an unauthenticated caller-owned baseline; returns real current NS/MX records, added/removed sets and tri-state target-provider transition. Current DNS comes from one bounded native recursive-resolver query; existing Dossier provides context. Resolver caching may apply; no account ownership or global migration-completion claim. Existing provider patterns are reused without new invented attribution. At most50records,domain253chars,9sbudget; DNSsubquery2s/oneattempt. Unknown provider remai

## Output

A structured response containing WHOIS registration data, DNS records (A, MX, NS, TXT, CNAME, etc.), mail policy details (SPF, DKIM, DMARC), TLS/SSL certificate metadata, discovered subdomains, and optionally a diff against a provided DNS baseline snapshot.
