The Stax Bill API is a REST-based HTTP API. It makes use of standard HTTP authentication, verbs, and error codes.

Stax Bill ensures the API platform is stable and performs well under the stresses of real-world use. New features are first launched against a private API resource. New API features are made public after the feature has been fully vetted in the Stax Bill Admin application.
