Google Fonts is a library of fonts for websites, with fonts released under open-source licenses for commercial and non-commercial projects. A website can add a font by linking a stylesheet and referencing it in CSS. Developers can also request font metadata in JSON through the REST-based Google Fonts Developer API; each request requires an API key. The API supports sorting by alphabet, date, popularity, style count, and trending growth, as well as filters for family, subset, and category. With capability=VF, it can return variable font files and available axis-range metadata. When a project needs only particular characters, the text parameter can reduce the requested font file size by up to 90%. Native Android apps can use the Font Provider in Google Play Services, supported from Android Jelly Bean API level 16 onward. Fonts can also be self-hosted for redistribution under their license terms. Google says its Web API is designed to limit data collection, storage, and use, and is not used to create end-user profiles or for advertising. The Developer API documentation is intended for developers with JavaScript knowledge.
