To give developers a choice of high-quality fonts when using the Font API, we have created the Google Font Directory. There you can browse our catalog of available fonts, learn about the font designers who created them, and copy the code required to use them on your web page.
The fonts in the directory are all released under open source licenses; you can use them on any non-commercial or commercial project.
