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.\n\nThis 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.\n\nAlternative 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.","tags":[],"capabilities":["whois-lookup","dns-records","ssl-certificate-grading","tech-stack-detection","security-header-audit","subdomain-discovery","redirect-tracing","parallel-execution","x402-payment"],"categories":["security","network","domain-intelligence"],"synonyms":["domain recon","domain OSINT","WHOIS lookup","DNS lookup","SSL check","tech stack fingerprint","security headers scan","subdomain enumeration","domain audit"],"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"],"endpointUrl":"https://domain.hugen.tokyo/domain/full","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","extra":{"name":"USD Coin","version":"2"},"payTo":"0x29322Ea7EcB34aA6164cb2ddeB9CE650902E4f60","amount":"10000","scheme":"exact","network":"eip155:8453","maxTimeoutSeconds":300},{"asset":"EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v","extra":{"feePayer":"GVJJ7rdGiXr5xaYbRwRbjfaJL7fmwRygFi1H6aGqDveb"},"payTo":"4du4AfkjJEwch2zk3shkPJVZfyJHNDnNjEWC6AboaS5Z","amount":"10000","scheme":"exact","network":"solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp","maxTimeoutSeconds":300}]},"qualityScore":"0.650","qualityRationale":"The endpoint is live (402 challenge confirmed) with a clear OpenAPI spec and sample response structure from the challenge.
