An Internationalized Domain Name

GEThttps://api.deepinfo.com/v1/discovery/domain-detail

The record of münchen.de, sent as its punycode form xn--mnchen-3ya.de: both forms come back, with is_idn: true.

Param: domain
Value: xn--mnchen-3ya.de

Asks for xn--mnchen-3ya.de, the ASCII (punycode) form of münchen.de.

The response carries both forms, punycode and unicode, and is_idn: true. name shows how Deepinfo reads the label: language de, the Latin spelling munchen in latinized, and contains_confusable: true (the name has a character that can be mistaken for another). The .de registry does not publish the registrar or the creation and expiry dates, so those WHOIS fields are null (the last update, May 15, 2025, is there); webdata.http.redirection_history follows the site to https://www.muenchen.de/. ssl is null: no certificate was recorded for this name.

In the response, look at unicode, name.latinized, name.contains_confusable and webdata.http.redirection_history.
