The objective of spire.io is to allow developers to build Web and mobile applications without having to also build the server-side infrastructure that is typically needed to support them. The server-side support provided by spire.io is centered upon providing infrastructure for developers through RESTful API's and scenario-specific client libraries.
The fundamental building blocks of spire.io's back-end support services are their channel and subscription resources, which essentially provide the backbone for communication and event listeners within the spire.io infrastructure.
Spire.io currently has two available services; Messaging, which provides the foundation of real-time capabilities to applications; and Identity, which allows developers to easily integrate user registration and log-in into their apps.

Though your definition of an SDK may differ, in our world, we define SDKs as platform- specific tools for consuming existing APIs of the sort we list in our API directory. For example, the Ruby SDK for consuming the Twitter Ads API.
