Mock sample for your project: Archive API

With the Article Search API, you can search New York Times articles from Sept. 18, 1851 to today, retrieving headlines, abstracts, lead paragraphs, links to associated multimedia and other article metadata.
Note: In URI examples and field names, italics indicate placeholders for variables or values. Brackets [ ] indicate optional items. Parentheses ( ) are not a convention — when URIs include parentheses, interpret them literally.

The Semantic API complements the Articles API. With the Semantic API, you get access to the long list of people, places, organizations and other locations, entities and descriptors that make up the controlled vocabulary used as metadata by The New York Times (sometimes referred to as Times Tags and used for Times Topics pages).
The Semantic API uses concepts which are, by definition, terms in The New York Times controlled vocabulary. Like the way facets are used in the Articles API, concepts are a good way to uncover articles of interest in The New York Times archive, and at the same time, limit the scope and number of those articles. The Semantic API maps to external semantic data resources, in a fashion consistent with the idea of linked data. The Semantic API also provides combination and relationship information to other, similar concepts in The New York Times controlled vocabulary.

With the Movie Reviews API, you can search New York Times movie reviews by keyword and get lists of NYT Critics' Picks.

The Geographic API extends the Semantic API, using a linked data approach to enhance location concepts used in The New York Times' controlled vocabulary and data resources which combine them with the GeoNames database, an authoritative and free to use database of global geographical places, names and features.

With the Times Newswire API, you can get links and metadata for Times articles and blog posts as soon as they are published on NYTimes.com. The Times Newswire API provides an up-to-the-minute stream of published items.

Get lists of NYT Articles based on shares, emails, and views.

The Books API provides information about book reviews and The New York Times bestsellers lists.

Get access to comments from registered users on New York Times articles. NOTE: This API is deprecated.

The Top Stories API provides lists of articles and associated images by section.

With the TimesTags API, you can mine the riches of the New York Times tag set. The TimesTags service matches your query to the controlled vocabularies that fuel NYTimes.com metadata. You supply a string of characters, and the service returns a ranked list of suggested terms.
