Retrieving a single DOI

Almost any meaningful use of the DataCite REST API will involve some level of record retrieval. The responses from each of your requests fall into two basic categories: Singletons (i.e., a single record) and Lists (i.e., a list of records). This section of the guide covers singletons, and the next section (Retrieving a list of DOIs) will cover lists.

Singletons are single results, e.g. the metadata for a specific DOI. For example, retrieving the metadata record for the DOI 10.14454/FXWS-0523 from the command line with cURL can be done as follows:

# GET /dois
$ curl https://api.datacite.org/dois/10.14454/FXWS-0523

The API reference provides example code for Node, Ruby, Javascript and Python.

The response would look like this:

        "id": "10.14454/fxws-0523",
        "type": "dois",
