The DataCite REST API allows users to retrieve, query and browse DataCite DOI (Digital Object Identifier) metadata records. The API is (generally) RESTFUL and returns results in JSON, as the API follows the JSON API specification. The DataCite REST API is not intended for creating DOIs or metadata records. The API does NOT require authentication.
Other alternatives to retrieve, query and browse DataCite DOI metadata records include DataCite OAI-PMH service and the DataCite Search service. OAI-PMH is used primarily for the bulk harvesting of metadata, and DataCite Search – which uses the DataCite REST API under the hood – provides a web interface to retrieve, query and browse DataCite metadata records.
DataCite is a global non-profit organization that provides persistent identifiers (DOIs) for research data. Their goal is to help the research community locate, identify, and cite research data with confidence.
