DataCite EZ API

The DataCite EZ API allows users to register DataCite DOI (Digital Object Identifiers) and associated metadata. The API is compatible with the EZID API from the California Digital Library and is intended for previous users of that API. However, the DataCite Metadata Store (MDS) API is the default API for registering DataCite DOIs.

To retrieve DOI metadata records users should use the DataCite REST API, which provides better performance, better query options, and doesn't require authentication

The API requires authentication and , only traffic via a secure connection (HTTPS) is supported. The DataCite EZ API uses HTTP Basic authentication. To become a member, interested parties should contact DataCite support.
