Cloud API tokens...RFC compliant?

Still working on an Ionic/AngularJS solution for logging into Particle. I don’t see understand how I can use the particle-api-js in my app so I have been looking at rolling my own Angular module or using an existing solution. Long term I will implement my own app/backend and use two-legged auth so I am leaning towards the module below. In the meantime does the particle cloud comply with any existing token RFC standards? No issue if not just makes it easier to find an appropriate module if so. Thanks.
