> domain.hugen.tokyo DNS Lookup is a paid API for AI agents from domain.hugen.tokyo, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-15).

Performs parallel DNS lookups across 3 independent resolvers for A, AAAA, MX, TXT, NS, CNAME, and SOA records with SPF/DMARC parsing and resolver inconsistency detection.

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-ae6ab8f0
```

Example prompt: Can you look up all DNS records for example.com using multiple resolvers in parallel — I want to see A, MX, TXT, NS records and check if SPF and DMARC are set up correctly, and flag any inconsistencies between resolvers that might indicate DNS hijacking?

## When to prefer this

Choose this endpoint when you need comprehensive DNS record data from multiple resolvers simultaneously, want to detect resolver inconsistencies (potential DNS hijacking signals), or need SPF and DMARC parsing included alongside raw DNS records — all in a single call rather than querying three separate resolvers and comparing manually.

## Known failure modes

- Domain does not exist — NXDOMAIN returned by resolvers
- All 3 resolvers fail to respond — timeout error
- Invalid domain format supplied — validation error
- Resolver inconsistency detected — partial results with flags indicating which resolvers disagreed

## How this service works

DNS lookup across 3 independent resolvers in parallel — A, AAAA, MX, TXT, NS, CNAME, SOA records. SPF mechanism parsing, DMARC policy extraction, resolver inconsistency detection (DNS hijacking/BGP leak signal). One call replaces 3 separate resolver queries + result comparison. Accepts USDC payments on Base and Solana

## Output

Returns DNS records (A, AAAA, MX, TXT, NS, CNAME, SOA) collected from 3 independent resolvers in parallel, parsed SPF mechanisms, extracted DMARC policy, and any detected inconsistencies between resolver responses that may signal DNS hijacking or BGP leaks.
