Full domain intelligence report: WHOIS, DNS, SSL, tech stack, headers, subdomains, and redirects in one call.
What it does
The `/domain/full` endpoint on domain.hugen.tokyo runs all seven domain intelligence checks in parallel and returns a combined report. The checks cover WHOIS registration data, DNS records, SSL certificate grading, technology stack detection, security header auditing, subdomain discovery, and redirect chain tracing. It accepts a single `domain` query parameter (e.g., `example.com`) via HTTP GET and returns a JSON object with sections for each analysis.
This is an x402-protocol endpoint priced at $0.02 USDC per call on the Base network. The sample response included in the 402 challenge shows the structure: WHOIS registrar info, DNS A records, SSL grade (A/B/etc.), technology count, security headers grade, subdomain count, and redirect grade. Individual sub-checks are also available as separate endpoints (`/domain/whois`, `/domain/dns`, `/domain/ssl`, `/domain/tech`, `/domain/headers`, `/domain/subdomains`, `/domain/redirect`) if you only need one piece of the report.
Alternative access methods include an MCP gateway at `mcp.hugen.tokyo/mcp`, a free API key with $0.05 credit via the discovery service, or the `x402-pay` Python SDK for wallet-free one-liner calls. The API is documented via OpenAPI 3.1 at `/openapi.json` and a Swagger UI at `/docs`. Response schemas for individual fields are not fully specified in the OpenAPI spec.
Capabilities
Use cases
- —Running a comprehensive domain audit before acquiring or partnering with a website
- —Automated security reconnaissance of target domains in a penetration testing workflow
- —Enriching threat intelligence feeds with domain registration, DNS, and SSL metadata
- —Verifying a domain's tech stack and security posture during vendor due diligence
- —Agent-driven domain analysis where all checks need to run in a single API call
Fit
Best for
- —AI agents needing a single-call comprehensive domain report
- —Security analysts performing quick domain reconnaissance
- —Developers building domain monitoring or alerting tools
Not for
- —Continuous real-time DNS monitoring (this is a point-in-time snapshot)
- —Deep vulnerability scanning or active exploitation testing
- —Bulk domain lookups at very high volume (per-call pricing may add up)
Quick start
pip install x402-pay
import x402_pay
r = x402_pay.get('https://domain.hugen.tokyo/domain/full?domain=example.com')

Quality
The endpoint is live (402 challenge confirmed) with a clear OpenAPI spec and sample response structure from the challenge. However, response schemas are empty in the OpenAPI definition, no detailed field-level documentation exists, and the sample response in the challenge appears to be a truncated preview rather than a full response. Pricing is clear at $0.02 USDC on Base.
Warnings
- —OpenAPI response schemas for all /domain/* endpoints are empty — no field-level documentation available
- —The sample response in the 402 challenge appears to be a summary preview; actual full responses may contain significantly more data
- —Root URL returns 404; no dedicated landing page or pricing page exists
