In a blog post on the release, Jeremie Lenfant-Engelmann, a software engineer on the Google Web Fonts team, said the team has received several requests from developers for a dynamic feed of the most recent Web fonts offered via Google Web Fonts.
"Such a feed would ensure that you can incorporate Google Web Fonts into applications and menus dynamically, without the need to hardcode any URLs," Lenfant-Engelmann said. "The benefits of this approach are clear. As Google Web Fonts continues to add fonts, these fonts can become immediately available within your applications and sites."
To meet developers' needs, Google created the Google Web Fonts Developer API, which provides a list of fonts offered via Google Web Fonts, Lenfant-Engelmann said. "Results can be sorted by alpha, date added, popularity, number of styles available and trending -- which is a measure of fonts growing rapidly in usage."
Lenfant-Engelmann added that some developers have helped Google test the new API over the last few months, and the results are already public. "Take a look at TypeDNA's photoshop plug-in as well as Faviconist, an app that makes generating favicons as simple as can be, and Google Web Fonts Families, a list of Google Web Fonts that have more than one style," he said.
