Retrieving a list of DOIs

The DataCite REST API can be used to retrieve lists of DOIs. List results can contain multiple entries and can be filtered by various parameters.

A list response has four parts:

  • data, which will contain the items matching the query or filter.
  • included, which will contain side-loaded associations, via the ?include=x parameter.
  • meta, which includes information about the query, e.g. number of results returned.
  • links, which includes links to the current and next page.

Working with lists

The next few guides will help you navigate list results:

Request

Retrieve a list of DOIs via a GET request to https://api.datacite.org/dois with optional parameters.

Parameters

The API Reference contains a complete list of query parameters that can be used to filter lists. Here are some of the most commonly used parameters:

Repository

This query retrieves all DOIs registered by a specific Repository account (only Findable DOIs are listed unless authentication is included).

# GET /dois
$ curl https://api.datacite.org/dois?client_id=datacite.datacite

Prefix

This query retrieves all DOIs registered with a specific prefix (only Findable DOIs are listed unless authentication is included).

# GET /dois
$ curl https://api.datacite.org/dois?prefix=10.5438

Member/Consortium Organization ID

This query retrieves all DOIs registered by a specific Member/Consortium Organization account (only Findable DOIs are listed unless authentication is included).

# GET /dois
$ curl https://api.datacite.org/dois?provider-id=datacite

Consortium Lead

This query retrieves all DOIs registered with by a specific Consortium account (only Findable DOIs are listed unless authentication is included).

# GET /dois
$ curl https://api.datacite.org/dois?consortium-id=tibco

Response

Findable DOIs will always be included. Draft records and Registered state DOIs can also be retrieved by authenticating to use the Member API.

The response would look like this:

To save space, the example response shows only two records in this list and the resource type "meta" counts.

What's in the API response?

The REST API response includes all metadata in JSON format as well as meta fields that provide aggregated information about the DOIs in the list.

👍

Note: Affiliation identifiers (supported in Metadata Schema 4.3+) are not included in REST API responses by default. To include affiliation identifier details, add &affiliation=true to your queries. See our FAQ for more information

The list below provides a description of the meta fields that appear in the API response. This information is different from the DOI metadata.

total
Total results count.

totalPages
Total pages count.

page
Current page.

states
Counts by DOI state.

resourceTypes
resourceTypes in the search results with counts.

created
Histogram of the create date of the DOI record by top 10 years with counts.

published
Histogram of publicationYear years with counts.

registered
Histogram of the registered date of the DOI record by top 10 years with counts.

providers
The top 10 DataCite Members or Consortium Organizations with Members IDs, Member titles, and counts.

clients
The top 10 repositories in the search results with repository IDs, repository titles, and counts.

affiliations
The top 10 represented ROR affliations with ROR ID, research organization title, and counts.

prefixes
The top 10 prefixes in the search with counts.

certificates
Repository certificates in the search with counts.

licenses
The top 10 rights with rights identifiers in the search with counts.

schemaVersions
The DataCite Metadata Schema versions represented in the search with counts.

linkChecksStatus
The status of the landing pages of DOIs in the search (when and if last checked) with counts.

subjects
The top 10 subjects represented in the search with counts.

fieldsOfScience
The top 10 Fields of Science and Technology (FOS) subjects in the search with counts.

citations
A histogram of citations by publicationYear in the search by top 10 years with counts.

views
A histogram of views by publicationYear in the search by top 10 years with counts.

downloads
A histogram of downloads by publicationYear in the search by top 10 years with counts.

Can I export the results in CSV format?

Including the text/CSV format in the header of the API call exports the results in CSV format. Add more filtering parameters to narrow or scope-out the file.

Other useful lists

There are many other resources in the API (see table below) and all of them can be retrieved in the same fashion. Major resource components supported by the DataCite API are (in alphabetical order) presented below and can be used alone like this:

ResourceDescription
/clientsreturns a list of all DataCite clients
/doisreturns a list of all DOIs (datasets, text documents, etc.)
/eventsreturns a list of all events from the DataCite Event Data service
/prefixesreturns a list of all DOI prefixes
/providersreturns a list of all DataCite providers
/reportsreturns a list of all usage reports

Results of queries are also returned as lists. The next section of this guide (Queries and Filtering) will cover making and filtering queries.
