Google Fonts
Metadata for all families served by Google Fonts.
About Google Fonts
The Google Fonts Developer API provides metadata for all font families served by Google Fonts, letting applications query available families through a REST endpoint that returns JSON data. Each family object includes fields such as name, subsets (supported scripts), variants (styles), version, last modified date, font files by variant, and optionally axes (for variable fonts) and tags. Requests require an API key appended as a query parameter.
The API supports sorting results alphabetically, by date added, by number of styles, by trending usage, or by popularity, and supports filtering by family name, subset, or category. It also supports optimization options, including retrieving font files in WOFF2 format and retrieving variable font files with axis range metadata via a capability parameter.
The documentation is intended for web and application developers and assumes knowledge of JavaScript.
