Anyone can request an API Key to use Elsevier APIs. Except for Scival and Embase APIs, access at no charge is available to researchers in academic, public-sector and not-for-profit institutions. Free access is only available for non-commercial use and provided Elsevier's policies for using APIs and the data are honoured.
Full API access is only granted to researchers affiliated to organisations that have subscriptions to the corresponding Elsevier product.
APIs are also available for OAuth authentication; for electronic holdings exchange in KBART format and for checking a user's access rights for specific publications. These APIs are made available to customers and partners upon request, subject to approval.
