# domain.hugen.tokyo Full Domain Intelligence

> domain.hugen.tokyo Full Domain Intelligence is a paid API for AI agents from domain.hugen.tokyo, paid per call via x402, $0.02/call, not verified (last probed 2026-10-13); live alternatives: Stable Domains Availability Checker ($0.05) and NetIntel Bulk Domain Availability Check ($0.1).

Agents call it through Zero, which pays per call: no API key and no wallet of your own. New accounts start with $5.

Live alternatives for the same use case:
- [Stable Domains Availability Checker](https://www.zero.xyz/c/stable-domains-availability-checker-d9c6e557) ($0.05)
- [NetIntel Bulk Domain Availability Check](https://www.zero.xyz/c/netintel-bulk-domain-availability-check-0a16e4f3) ($0.1)

Runs all 7 domain analysis checks in parallel — WHOIS, multi-resolver DNS, SSL/TLS, tech stack, security headers, subdomain discovery, and redirect chain — returning aggregated results with an overall security grade

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-hugen-tokyo-481d1e64
```

Example prompt: Give me a full domain intelligence report for stripe.com — I want WHOIS, DNS records, SSL certificate details, tech stack, security headers, any subdomains, and the redirect chain all in one shot with an overall security grade.

## When to prefer this

Use this endpoint when you need a comprehensive domain profile and want to avoid making 7 separate API calls and aggregating results yourself. Ideal for security audits, due diligence on unknown domains, onboarding checks, or any workflow where a single parallel-executed, aggregated domain report with a weighted security grade is more efficient than piecemeal lookups.

## Known failure modes

- Domain does not exist or is unreachable — partial results returned for components that succeeded
- Individual component timeout — that component's result is omitted but others are included
- Invalid domain format provided — request rejected with validation error
- Network error reaching target domain — affected checks may return empty or error state
- Rate limiting or payment failure — request not processed

## How this service works

Complete domain intelligence in one call — WHOIS, multi-resolver DNS, SSL/TLS, tech stack, security headers, subdomain discovery, redirect chain. All 7 run in parallel with individual timeouts. Partial results on component failure. Weighted overall security grade. Doing this yourself requires 7 separate tools and result aggregation. Accepts USDC payments on Base and Solana

## Output

A unified JSON response containing: WHOIS registration data (registrar, dates, name servers), DNS records from 3 resolvers (A, AAAA, MX, TXT, NS, CNAME, SOA), SSL/TLS certificate details (issuer, SANs, expiry, days remaining), detected technology stack (web server, CMS, frameworks, CDN, analytics), security header audit (10 headers scored), discovered subdomains from certificate transparency logs, redirect chain (up to 10 hops with timing and status codes), and a weighted overall security grade. Partial results are returned if any individual component fails.
