Diffbot Analyze API
https://www.diffbot.com/dev/docs/analyze/

The Diffbot Analyze API visually analyzes a web page, identifies its “page-type,” and determines which Diffbot extraction API (if any) is appropriate. Pages that match a supported extraction API — articles, discussions, images, products or videos — will be automatically extracted and returned in the Analyze API response. Pages not currently supported by an extraction API will return “other.” This will be added to Bot Research Subject Tracer™. This will be added to Web Data Extractors 2018 white paper. This will be added to Business Intelligence Resources Subject Tracer™. This will be added to Entrepreneurial Resources Subject Tracer™. This will be added to the tools section of Research Resources Subject Tracer™.
