Many scientific publishers, databases and products offer tools that allow users to programmatically access, analyse, extract and use metadata, data and full text for various research purposes.
APIs (Application Programming Interfaces) are programming interfaces that serve as an access point for retrieving and exchanging data. They provide commands and functions that make it easier to access and work with data.
Listed below are some of the frequently used scientific resources and the respective access information.
Please note: many providers limit the number of accesses per minute and/or day. If you need more than the free quota, please contact the provider in advance, otherwise the services may be blocked for FAU.
If you have any further questions, or if you are missing a resource from this list, please ask a librarian.
Metadata records for more than 4 million documents from IEEE journals, conference proceedings and technical standards
Tools:
Metadata Search API - provides access to metadata records for more than 5 million documents from IEEE journals, conference proceedings and technical standards.
IEEE Open Access API - provides full text access to Open Access articles
Digital Object Identifier (DOI) API - provides access to metadata records for a maximum of 25 DOIs including abstracts
API-Aufrufe erfolgen über HTTP mit strukturierten URL-Abfragen.
10 API-Aufrufe pro Sekunde und 200 Aufrufe pro Tag möglich
Perform real-time checks of bibliographic metadata such as DOI, author, source title, etc. with the Web of Science core collection and other Web of Science product databases. This enables the creation of links at article level to the Web of Science Database using third-party systems and the retrieval of citation frequencies from the Web of Science Database.
Tools:
WoS Researcher API – maximum 5 requests per second and 5,000 per day
WoS Starter API - 1 access per second and 50 per day free of charge
Access to the ADS database with bibliographic data of more than 15 million publications in the fields of astronomy and astrophysics, physics and general science, including all arXiv e-prints. Summaries and full texts of the most important astronomy and physics publications are indexed and searchable.
PMC offers several APIs that provide programmatic access to various services that deal with PMC literature content, including file validation tools, open access web services and an ID converter that converts PMCIDs, PMIDs, manuscript IDs and DOIs to each other.
