The fonts, including any derivative works, can be bundled, embedded, redistributed and/or sold with any software provided that any reserved names are not used by derivative works. The fonts and derivatives, however, cannot be released under any other type of license. The requirement for fonts to remain under this license does not apply to any document created using the fonts or their derivatives.

Request Limits: "There is no request limit, but we reserve the right to reject API requests. This applies especially to requests we consider abusive or inappropriate (i.e. if it seems to be a DoS attack). We therefore record the origin of all requests (referrer and IP address), but not the contents of the QR codes"
