The Stripe Python Library by Stripe is a REST resource. The library API is designed for predictable, resource-oriented URLs and HTTP response codes to indicate API errors. Further, it is aims to support the built-in HTTP features, like HTTP authentication and HTTP verbs with off-the-shelf HTTP clients, and the support cross-origin resource sharing to allow interaction with the API from a client-side web application. The returns are in JSON, including errors.
Customer service-focused Zappos intends to make public a feature of its Zappos API that allows customers to access order history. The feature is currently available in its official iPhone and iPad apps, though there is no timeline for when Zappos will make it available to its growing developer community.
