The W3C The Permissions API is a document that specifies an API for handling permissions. It allows web applications to know whether a given permission has been granted or denied, or if a user will be asked whether a given permission should be granted. This document is a work in progress and may be replaced or rendered obsolete at any time.
We've added 20 APIs to the ProgrammableWeb directory in categories such as Translation, Real Estate, Authentication, and Electronic Signature. One highlight today is the AimBrain API, which offers biometric authentication services to developers. Have a look at the latest offerings.
