This guide was adapted from the MIT Libraries' APIs for Scholarly Resources and NCSU Libraries' Scholarly APIs and Datasets guides.

APIs

An API (application programming interface) is an online tool to access information or to download raw data. Many databases and publishers make APIs available for users to extract data for scholarly purposes. This guide lists some of the resources available at Tufts that provide API access, either on a full-text basis or for limited retrieval of information.

Resources on this guide are divided into two categories: those that provide access to full-text, complete datasets, or other complete objects via the API, and those where you are able to access large sets of bibliographic data or other metadata for articles and other objects.

Programming skills are required to use many of these APIs.

Access to full-text, full datasets, or other complete objects

Alpha Vantage Stock API
Financial and economic datasets grouped into four categories: (1) Time Series Stock APIs, (2) Fundamental Data, (3) Physical and Digital/Crypto Currencies (e.g., Bitcoin), and (4) Technical Indicators. See also this API review article that describes the general best practices of working with financial and economic datasets.
arXiv
Programmatic access to arXiv's e-print content and metadata, with a focus on physics, mathematics and computer science.
Caselaw Access Project
U.S. court decisions digitized from the collection of the Harvard Law Library. Case metadata, such as the case name, citation, court, date, etc., is freely and openly accessible without limitation. Full case text can be freely viewed or downloaded but you must register for an account to do so, and currently you may view or download no more than 500 cases per day. In addition, research scholars can qualify for bulk data access by agreeing to certain use and redistribution restrictions.
CORE API
CORE harvests, maintains, enriches and makes available metadata and full-text content (typically a PDF) from many Open Access journals and repositories.
Data.gov APIs
A catalog of APIs from across the government.
Dataverse APIs
Mutliple APIs are available to access data and metadata in the Dataverse repository.
Google Books API Family
Programmatic access to many of the operations available on Google Books website, including searching and browsing through the list of books that match a given query, and viewing information about a book, including metadata, availability and price.
HathiTrust Data API
Can be used to retrieve content (page images, OCR, and in some cases whole volume packages), as well as metadata for HathiTrust volumes.
Library of Congress APIs & Data
A variety of APIs & bulk data download from Library of Congress collections, including Congress.gov data, newspapers, public radio & TV programs, and primary materials from cultures & countries around the world.
Metropolitan Museum of Art Collection API
Access to all of The Met’s Open Access data and to corresponding high resolution images (JPEG format) that are in the public domain.
National Library of Medicine (NLM) Eresources
A suite of APIs, data sets, and other tools to access NLM databases.
Organisation for Economic Co-operation and Development (OECD) API
Programmatically access a selection of top-used datasets covering data for OECD countries and selected non-member economies.
PLoS API
Multiple methods to access the PLoS article corpus and article metadata.
ScienceDirect APIs
Researchers at subscribing academic institutions can text mine subscribed full-text ScienceDirect content via the Elsevier APIs for non-commercial purposes.
Springer & BioMed Central API
Multiple APIs offer access to journal article metadata in Springer titles and BioMed Central, and full-text where available from Springer Open Access titles.
World Bank APIs
Three different APIs to provide access to different datasets: one for Indicators (or time series data), one for Projects (or data on the World Bank’s operations), and one for the World Bank financial data (World Bank Finances API).

Access to bibliographic data or other metadata

CrossRef REST API
Exposes metadata about articles provided to CrossRef, including bibliographic data, funding data, license information, full-text links, ORCID iDs, and abstracts.
Digital Public Library of America (DPLA) API
Access to metadata for millions of objects from libraries, archives, and museums.
Elsevier APIs
Provides access to citation data and other metrics from Scopus, ScienceDirect and SciVal.
Europeana APIs
Multiple APIs offer access to metadata and user annotations for objects from Europe's libraries, museums, and archives.
The General Index
An index of words and short phrases contained in more than 100 million journal articles. It consists of a listing of n-grams, from unigrams to five-grams, extracted from 107 million journal articles.
IEEE Xplore Metadata APIs
Provides access to metadata for more than 4 million documents available in the IEEE Xplore® Digital Library, including IEEE Journals, Conference Proceedings, Books / eBooks, Courses and Standards.
JSTOR Data for Research
Provides datasets of content on JSTOR for use in research and teaching. Data available through the service includes metadata, n-grams, and word counts for most articles and book chapters, and for all research reports and pamphlets on JSTOR.
SAO/NASA Astrophysics Data System
The ADS Developer API allows you to write scripts that access many ADS capabilities such as the search, metrics, and export functions. ADS is a Digital Library portal for researchers in Astronomy and Physics.
