# API The Zonemaster GUI provides an API to access specific resource and perform specific tasks by adding a path to the Zonemaster GUI base URL, e.g. `https://zonemaster.net/`. For the paths the following keys are used: * ``: A [Language Code][Language Codes] * ``: A string of 16 characters in `0-9a-f` (hexadecimal) * ``: A domain name to be tested (temporarily not supported) The supported paths are the following: * `//result/`: access the result page with results for the test with `` in the selected language, e.g. `https://zonemaster.net/en/result/7e363fb606343397`. * `//faq`: access the FAQ in the selected language, e.g. `https://zonemaster.net/en/faq`. * `/api`: With JSON RPC call access the Zonemaster [Backend RPC-API], e.g. `https://zonemaster.net/api`. The GUI will redirect from `` (e.g. `https://zonemaster.net/`) to `/` (`https://zonemaster.net/en/`) automatically using the user browser language, if supported and configured by the installation. Else it uses the default language defined in Zonemaster-GUI. The following paths are temporarily not supported: * `/run-test`: access the input form. * `/run-test/`: populate the input form with ``. ## Language Codes Zonemaster uses [ISO 639-1] two-letter language codes, in lower case. A default installation of Zonemaster-GUI currently has support for the following language codes and languages: * `da` for Danish language * `en` for English language, the default language in a default installation * `es` for Spanish language * `fi` for Finnish language * `fr` for French language * `nb` for Norwegian language * `sl` for Slovenian language * `sv` for Swedish language A non-default installation may have support for only some of the languages or maybe other languages.
