Below is a list of scholarly databases and collections that offer some form of API access, online tools to access data, or raw data downloads. (What's an API?)
arXiv API
API access to Cornell's open-access arXiv e-print repository, used primarily by physics, mathematics and computer science communities to share cutting-edge research.
Digital Public Library of America (DPLA) API Codex
Access data from the DPLA repostiory of cultural and scientific knowledge, including partner data from Harvard, NY Public Library, ARTstor, the David Rumsey Historical Map collection and more. Zipped json files of partner data and the entire repository are available for bulk download.
Google Books Ngram Viewer datasets
The Google Books Ngram Viewer provides a frontend to explore word counts from the entire corpus of digitized Google books. Google also provides access to the thousands of raw datasets on which the Viewer operates.
JSTOR Data for Research
Not an API per se, but you can use DFR to select and interact with data and metadata from JSTOR's archive of scholarly journal literature (more than 7 million journal articles) and primary resources (26,000 19th Century British Pamphlets).
ORCID API
Query the ORCID researcher identifier system (including individual researchers, universities, national laboratories, commercial research organizations, research funders, publishers, national science agencies, data repositories, and international professional societies) to obtain researcher profile data.
Springer API Portal
Robust set of APIs for metadata, images and articles from this scientific publisher of books and journals, including close to 500 academic and professional society journals.
UN Comtrade Web Services
Access data from the United Nations Commodity Trade Statistics database, including International Merchandise Trade Statistics (IMTS) and the work of the International Merchandise Trade Statistics Section (IMTSS) of the United Nations Statistics Division.
Web of Sciences Web Services
Query over 8,000 of the leading journals in the arts, humanities, sciences and social sciences, indexed by Web of Science to return limited article information including article title, authors, source data, and author supplied keywords. (UCB access)
Worldbank APIs
Three 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).
[Much of the above was adapted from Mark Clemente's excellent guide to APIs for Scholarly Resources at MIT.]
