Font Squirrel can help you and your applications find new fonts. The Font Squirrel API allows users to retrieve hundreds of fonts that are "font-face-ready," which can be used on web sites using CSS or CSS3. The API provides categorical listings, font lists and the ability to download complete sets of @font-face fonts. Font Squirrel uses RESTFul calls and responses are formatted in JSON.
