The Pwinty Python SDK by Matt Gorecki allows API interaction, providing resources to work with orders, photos, documents, stickers, and errors. Pwinty is the photo printing API solution that allows to create photo prints, wall art, photobooks, and merchandise.
You may remember the full featured, unpublished API from popular mobile photo sharing site Instagram that we covered last month. The interface was reverse engineered by a developer and today Instagram asked anyone using its private, unofficial Instagram API to stop. At the same time, it announced a beta public API would be coming soon.
Popular iPhone photo-sharing app Instagram is a prime candidate for an API, which is probably why it already has one. Though documentation refers to it as an "unofficial" Instagram API, the fact that it uses the company's own servers makes it seem pretty official. Instagram has not launched the API, nor is an API linked from its home page. Yet, it has a mobile app and right column Twitter integration, both of which likely consume the API.
