# Domain Parse – Label Splitting, Punycode & Lookalike Detection

> Domain Parse – Label Splitting, Punycode & Lookalike Detection is a paid API for AI agents from domain-dns.x402tookit.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-25).

Parses a domain or URL into its constituent labels, registrable domain, and subdomain; converts punycode to unicode; and flags internationalized and lookalike traits.

## 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-parse-label-splitting-punycode-lookalike-detection-4bf57fbc
```

Example prompt: Can you parse 'https://www.bbc.co.uk/news' and tell me its registrable domain, subdomain, TLD suffix, and whether it uses any internationalized or lookalike characters?

## When to prefer this

Choose this endpoint when you need structural decomposition of a domain or URL — splitting into labels, registrable domain, subdomain, and suffix — along with punycode-to-unicode conversion and IDN/lookalike flagging. It is the right choice for phishing detection pipelines, URL normalization, and security screening workflows. Prefer it over DNS record lookups (which resolve live DNS) or WHOIS/RDAP lookups (which return registration data); this endpoint is purely a parse-time structural analysis requiring no live DNS queries.

## Known failure modes

- Invalid or unparseable domain string returns null fields or an error verdict
- Punycode conversion failure for malformed internationalized labels
- Missing 'domain' query parameter returns a 400-level error
- Very long or deeply nested domains may exceed parsing limits
- Newly registered TLDs not yet in the public suffix list may produce incorrect registrable domain splits

## How this service works

Split a domain or URL host into labels, registrable domain and subdomain; convert punycode and flag lookalike traits.

## Output

Returns a structured object containing: domain labels array, label count, registrable domain, subdomain, TLD suffix, ASCII and unicode representations of the domain, domain length, internationalized flag, a lookalike/verdict field with reasons, a human-readable summary, and metadata like source and timestamp. Also includes a disclaimer and a list of any checks not performed.
