The official MercadoLibre Python SDK by MercadoLibre calls the MercadoLibre RESTful API which provides tools to create an online store. This SDK is used to handle the OAuth WebServer flow, and there is no JSON parsing.
Local marketplace Zaarly has launched a Zaarly API for adding Zaarly buttons to any website. "Zaarly Anywhere" allows users to request products from someone nearby, such as from simple errands to complex products.
It's time to start shopping around for another API to search for deals, prices and reviews. That it, if you use the Yahoo Shopping API (our Yahoo Shopping API profile). On March 11 Yahoo's service will be discontinued, replaced by a "strategic partnership" that will leave developers sniffing for deals elsewhere.
