It is part of a broader Domain Intelligence API that offers 7 checks (WHOIS, DNS, SSL, tech stack, security headers, subdomains, redirects), each available individually or combined via `/domain/full`. This specific endpoint accepts a `domain` query parameter and returns structured JSON with DNS record data including A records, MX records, SPF information, and resolver inconsistency checks.\n\nThe endpoint is gated by the x402 payment protocol, requiring $0.01 USDC on the Base network per request. The 402 challenge response includes a sample of the actual output format, showing fields like `exists`, `records` (with A and MX arrays), `spf` (with raw SPF string), and `resolver_inconsistencies`. Alternative access methods are available: an MCP gateway at mcp.hugen.tokyo, API key-based access via discovery.hugen.tokyo, or the `x402-pay` Python SDK.\n\nThe API is documented via an OpenAPI 3.1 spec and a Swagger UI at `/docs`. Response schemas for the DNS endpoint are not fully specified in the OpenAPI definition (empty schema objects), but the x402 challenge sample provides a concrete example of the output structure. The service runs on Base network for payment settlement.","tags":[],"capabilities":["dns-lookup","a-record-query","mx-record-query","spf-check","resolver-inconsistency-detection","x402-payment","base-network-settlement","openapi-3.1"],"categories":["dns","domain-intelligence","networking"],"synonyms":["DNS records API","domain DNS lookup","DNS query service","A record lookup","MX record lookup","SPF record check","domain name resolution","DNS intelligence"],"warnings":["Response schema is not defined in the OpenAPI spec (empty schema object); output structure is inferred from the x402 challenge sample only.","No dedicated documentation beyond the Swagger UI at /docs; /pricing, /README, and /api all return 404.","Root URL returns 404 — no landing page for the service."],"endpointUrl":"https://domain.hugen.tokyo/domain/dns","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","extra":{"name":"USD Coin","version":"2"},"payTo":"0x29322Ea7EcB34aA6164cb2ddeB9CE650902E4f60","amount":"5000","scheme":"exact","network":"eip155:8453","maxTimeoutSeconds":300},{"asset":"EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v","extra":{"feePayer":"BENrLoUbndxoNMUS5JXApGMtNykLjFXXixMtpDwDR9SP"},"payTo":"4du4AfkjJEwch2zk3shkPJVZfyJHNDnNjEWC6AboaS5Z","amount":"5000","scheme":"exact","network":"solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp","maxTimeoutSeconds":300}]},"qualityScore":"0.650","qualityRationale":"The endpoint is live (402 challenge confirmed) with a valid OpenAPI 3.1 spec and working Swagger docs.
