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
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")
There are no API restrictions. However, providing an email address is required and a rate limit of 100k is suggested. If you need to access more data, use the data dump instead.
This package also has a RStudio Addin for easily finding free full-texts in RStudio.
