## 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-parser-public-suffix-list-e071aafb -d '<json body>'
```

Example prompt: Can you parse the domain 'mail.example.co.uk' and tell me its TLD, second-level domain, and subdomain?

## When to prefer this

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.

## Known failure modes

- 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

## 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
