This endpoint structures the APOD imagery and associated metadata so that it can be repurposed for other applications. In addition, if the concept_tags parameter is set to True, then keywords derived from the image explanation are returned. These keywords could be used as auto-generated hashtags for twitter or instagram feeds; but generally help with discoverability of relevant imagery

Introduction
This API returns data regarding almost all nouns in vedic literature. The results are JSON objects that contain the word transliterated to the Roman script, the word in the Nagari script, the meaning of the word, and the category the word belongs to. Proper nouns are not included (yet).
The API uses the Swagger 2.0 specification.
Authentication
This is an open API.

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.
