info:
  title: NewsBlur authentication classifiers API
  description: NewsBlur is a personal news reader (RSS/Atom aggregator) that brings people together to talk about the world. The HTTP API exposes account, feed, story, social ("blurblog"), intelligence-classifier, and OPML import/export operations. This OpenAPI description was generated by API Evangelist from the publicly documented endpoint reference at https://www.newsblur.com/api and the open-source NewsBlur codebase (github.com/samuelclay/NewsBlur). It is a faithful structuring of the documented surface, not a provider-published spec.
