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.

The Socrata OpenDataNetwork (ODN) REST API exposes public data, often continuosly updated and enhanced, from many thousands of public
government and non profit agencies.
Much of this data originating from independent sources is fused together to create new, and often
powerful, entity level data. The API, in addition to search and autosuggest capabilities for finding datasets,
enables data based comparisons across geographical regions such as states, counties, metropolitan areas,
cities and zip codes using highly vetted data providers such as US Census, BEA, HUD and others. Comparison data
is preformatted for easy and efficient display on a chart, graph or interactive map.
The API also exposes data organized by narrative style questions a human might ask. The questions can
be rapidly found using an autosuggest style index, and then used to directly access all data needed to
thoroughly and authoritatively answer the question. Retrieved data includes time series (temporally aligned),
tabular, map heavy (includes spatial boundaries), and auto generated unstructured descriptive text.
The ODN API does not duplicate API endpoints or services provided by public sector agencies, but rather,
returns context relevant pre-populated REST URLs, when appropriate, so the caller can access data
directly from the source.
The open source API powers OpenDataNetwork.com, an open source
site; the site highlights myriad uses and provides API badges with contextually relevant API example
REST endpoints and documentation pointers.
Finally, we continuously add new dat sources which appear automatically in the API, so if your favorite data
source is not available, check back soon. You can also join us HERE
and receive updates or let us know which data sources you are most interested in.
App Tokens
Registering for and including a Socrata application token
is required for the ODN API. They can be passed either using the app_token parameter
or the X-App-Token HTTP header.

You can use the CORE API to access the
resources harvested and enriched by CORE. If you encounter any problems with the API, please report them to us.
Overview
The API is organised by resource type. The resources are articles,
journals and repositories and are represented using JSON data format. Furthermore,
each resource has a list of methods. The API also provides two global methods for accessing all resources at once.
Response format
Response for each query contains two fields: status and data.
In case of an error status, the data field is empty. The data field contains a single object
in case the request is for a specific identifier (e.g. CORE ID, CORE repository ID, etc.), or
contains a list of objects, for example for search queries. In case of batch requests, the response
is an array of objects, each of which contains its own status and data fields.
For search queries the response contains an additional field totalHits, which is the
total number of items which match the search criteria.
Search query syntax
Complex search queries can be used in all of the API search methods.
The query can be a simple string or it can be built using terms and operators described in Elasticsearch
documentation.
The usable field names are title, description, fullText,
authors, publisher, repositories.id, repositories.name,
doi, oai, identifiers (which is a list of article identifiers including OAI, URL, etc.), language.name
and year. Some example queries:
title:psychology and language.name:English
repositories.id:86 AND year:2014
identifiers:"oai:aura.abdn.ac.uk:2164/3837" OR identifiers:"oai:aura.abdn.ac.uk:2164/3843"
doi:"10.1186/1471-2458-6-309"
Retrieving the latest Articles
You can retrieve the harvested items since specific dates using the following queries:
repositoryDocument.metadataUpdated:>2017-02-10
repositoryDocument.metadataUpdated:>2017-03-01 AND repositoryDocument.metadataUpdated:
Sort order
For search queries, the results are ordered by relevance score. For batch
requests, the results are retrieved in the order of the requests.
Parameters
The API methods allow different parameters to be passed. Additionally, there is an API key parameter which is common to all API methods. For all API methods
the API key can be provided either as a query parameter or in the request header. If the API key
is not provided, the API will return HTTP 401 error. You can register for an API key here.
API methods

OPA provides policy-based control for cloud native environments. The following endpoints (such as PUT /v1/policies) provide reference documentation for the OPA REST 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.
