roadoi interacts with the Unpaywall REST API, an openly available web-interface which returns metadata about open access versions of scholarly works.
This client supports the most recent API Version 2.
API Documentation: https://unpaywall.org/products/api
How do I use it?
Use the oadoi_fetch() function in this package to get open access status information and full-text links from Unpaywall.
roadoi::oadoi_fetch(dois = c("10.1038/ng.3260", "10.1093/nar/gkr1047"),
email = "najko.jahn@gmail.com")
