Diffbot's Extract API is a service that structures and normalizes data from web pages.

Unlike traditional web scraping tools, Diffbot Extract doesn't require any rules to read the content on a page. It uses a computer vision model to classify a page into one of 20 possible types, and then transforms raw HTML markup into JSON. The resulting structured JSON follows a consistent type-based ontology, which makes it easy to extract data from multiple different web sources with the same schema.

See a usage example.
