The blog post discusses the use of the unofficial Netflix API, known as the uNoGS API, accessible through RapidAPI, as the official Netflix API was deprecated in 2014. The uNoGS API allows developers to search Netflix's global catalog of TV shows and movies by accessing various endpoints that provide details on country-specific releases, expiring titles, and more. The guide provides a step-by-step process for integrating the Netflix API with Python, including signing up for a RapidAPI account, subscribing to a pricing plan, and selecting code snippets to use in applications. It also touches on related topics such as the rationale behind Netflix's closure of its public API program, the availability of APIs from other streaming services like Hulu and Rotten Tomatoes, and the role of RapidAPI as a comprehensive marketplace for APIs.
