How this service works
Split a domain into TLD/SLD/subdomain using the official Public Suffix List
Output
Returns the domain broken into its constituent parts: the public suffix (TLD), the second-level domain (SLD/registrable domain), and any subdomain, as determined by the official Public Suffix List
Example use cases
Extract registrable domain from user input
“I have a full hostname like 'api.beta.mycompany.com.au' — can you break it down so I can see the TLD, the registrable domain, and the subdomain separately?”
Classify email domain structure
“I'm processing a list of email addresses and need to separate the subdomain from the root domain for 'mail.signup.bigcorp.co.jp' — can you parse that out?”
Validate and normalize URL hostnames
“Before storing this hostname in our database, can you parse 'cdn.assets.shop.example.de' using the Public Suffix List to confirm the TLD and get the SLD and subdomain?”
Technical details
Endpoint
POSThttps://domain-parser.nordman-tehau.workers.dev/v1/domain/parseWhen to prefer
Choose this endpoint when you need accurate domain decomposition based on the authoritative Public Suffix List, especially for multi-part TLDs like .co.uk, .com.au, or .gov.br where naive string splitting would fail. It is preferable over regex-based approaches or simple string splitting for any domain parsing that must handle country-code and multi-label TLDs correctly.
Side effects
- Invalid or malformed domain name returns an error
- Domain with unrecognized TLD not in the Public Suffix List may fail or return unexpected results
- Empty input or missing 'domain' field returns a validation error
- Domains with trailing dots or special characters may cause parsing errors
