The Fontsource API allows developers to query information about fonts which the repository supports.
Note: The API servers are kindly sponsored by our friends at JSDelivr. We recommend using them as other CDNs may impose restrictions due to certain package sizes exceeding their limits.

Each route can also have additional queries included with the URL to filter the responses appropriately.
