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.
Example use cases
Phishing URL triage for security tool
“I got a suspicious link — can you break down 'https://paypal-secure.xn--pypal-4ve.com' into its domain labels and registrable domain, and tell me if it looks like an IDN homograph or lookalike attack?”
Data pipeline domain normalization
“I have a URL 'https://www.amazon.co.uk/products/shoes' — can you extract just the registrable domain and subdomain so I can normalize it in my dataset?”
Browser extension hostname analysis
“Parse the domain 'subdomain.münchen.de' for me — I need the unicode form, the ASCII punycode version, and a breakdown of its labels and suffix.”
Technical details
Endpoint
GEThttps://domain-dns.x402tookit.com/domain-parse?utm_source=zero.xyzWhen to prefer
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.
Side effects
- 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
