Hi Eric, I personally have used the Scopus API to identify the OA status of articles, and Scopus gets its data from Unpaywall (according to the Scopus documentation). A subscription to Scopus is required for this.
Unpaywall has an API but I haven't looked into the documentation to see if it is possible to get this data: https://unpaywall.org/products/api Regards, Roger ________________________________ From: Code for Libraries <CODE4LIB@LISTS.CLIR.ORG> on behalf of Eric Lease Morgan <emor...@nd.edu> Sent: January 26, 2023 11:14 AM To: CODE4LIB@LISTS.CLIR.ORG <CODE4LIB@LISTS.CLIR.ORG> Subject: [CODE4LIB] check for open access Given bibliographic metadata such as author, article title, journal title, date, etc., how can one programmatically go about learning whether or not the given article has been published as open access? I suppose I could query something like SHERPA. No? What might you suggest? --Eric Morgan, University of Notre Dame
