TLD Email Extractor Free REST API
Query this REST API with any email address and it will extract and return the top level domain (TLD) against Mozilla TLDs official listing. It supports a range of scenarios with domains and subdomains, including .edu, .co.uk, and others. It also supports parsing unknown tlds.
The code is based on the tld-extract library, which in turn is a port of a yks/PHP library. The docs are simple: the API accepts only 1 query parameter - emailaddress - and returns JSON with the extracted TLD, and the email queried back.
For example: https://www.sevenj.com/rosterapi/v1/tld-extract?emailaddress=tom.jones@mail.company.com, will return the following:
{
"tld": "company.com",
"emailaddress": "tom.jones@mail.company.com"
}
