Data services for scientific resources
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.
