Zenodo

API Documentation for developers

Zenodo currently offers two different APIs:

  • REST API — includes support for uploading your research outputs.
  • OAI-PMH API — allows you to harvest all or parts of Zenodo via the OAI-PMH protocol.

REST API upload your research outputs

Introduction

The REST API allows you to programmatically upload and publish research outputs on Zenodo, with the same functionality which is available in our Upload user interface.

This short guide will give a quick overview of how to upload and publish on Zenodo, and will be using Python together with the Requests package.

  1. First, make sure you have the Requests module installed:

    $ pip install requests

  2. Next, fire up a Python command prompt:

    $ python
Python 2.7.5+
[GCC 4.8.1] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>>

  3. Import the requests and json modules (don't type the >>>-part):

    >>> import requests
>>> import json

  4. Try to access the API:

    >>> r = requests.get("https://zenodo.org/api/deposit/depositions")
>>> r.status_code
401
>>> r.json()
{u'status': 401, u'message': u'Unauthorized'}
  5. All API access requires an access token, so create one.

  6. Let's try again (replace ACCESS_TOKEN with your newly created personal access token):

    >>> r = requests.get("https://zenodo.org/api/deposit/depositions?access_token=ACCESS_TOKEN")
>>> r.status_code
200
>>> r.json()
[]

    Note, if you already uploaded something, the output will be different.

  7. Next, let's create a new empty upload:

    >>> headers = {"Content-Type": "application/json"}
>>> r = requests.post("https://zenodo.org/api/deposit/depositions?access_token=ACCESS_TOKEN", data="{}", headers=headers)
>>> r.status_code
201
>>> r.json()
{u'files': [], u'title': u'', u'created': u'2013-11-14T18:34:08+00:00', u'modified': u'2013-11-14T18:34:08+00:00', u'state': u'unsubmitted', u'owner': 1, u'id': 1234, u'metadata': {}}
>>> deposition_id = r.json()['id']

  8. Now, let's upload a new file:

    >>> data = {'filename': 'myfirstfile.csv'}
>>> files = {'file': open('/path/to/myfirstfile.csv', 'rb')}
>>> r = requests.post("https://zenodo.org/api/deposit/depositions/%s/files?access_token=ACCESS_TOKEN" % deposition_id, data=data, files=files)
>>> r.status_code
201
>>> r.json()
{u'checksum': u'2b70e04bb31f2656ce967dc07103297f', u'filename': u'myfirstfile.csv', u'id': u'eb78d50b-ecd4-407a-9520-dfc7a9d1ab2c', u'filesize': u'27'}

    Maximum file size is 2GB per file.

  9. Last thing missing, is just to add some metadata:

    >>> data = {"metadata": {"title": "My first upload", "upload_type": "poster", "description": "This is my first upload", "creators": [{"name": "Doe, John", "affiliation": "Zenodo"}]}}
>>> r = requests.put("https://zenodo.org/api/deposit/depositions/%s?access_token=ACCESS_TOKEN" % deposition_id, data=json.dumps(data), headers=headers)
>>> r.status_code
200

  10. and, we're ready to publish:

    Don't execute this last step - it will put your test upload straight online.
    >>> r = requests.post("https://zenodo.org/api/deposit/depositions/%s/actions/publish?access_token=ACCESS_TOKEN" % deposition_id)
>>> r.status_code
202

Testing

We provide a sandbox environment where you can test your API integration during development. The sandbox environment is available at http://sandbox.zenodo.org.

Please note that the sandbox environment can be cleaned at anytime. Also, the sandbox environment will issue test DOIs using the 10.5072 prefix instead of Zenodo's normal prefix (10.5281).

Versioning

The REST API is versioned. We strive not to make backward incompatible changes to the API, but if we do, we release a new version. Changes to the API are documented on this page, and advance notification is given on our Twitter account.

Authentication

All API requests must be authenticated and over HTTPS. Any request over plain HTTP will fail. We support authentication with via OAuth 2.0.

Acquiring a personal access token

  1. Register for a Zenodo account if you don't already have one.
  2. Go to your Applications, to create a new token.
  3. Select the OAuth scopes you need (for the quick start tutorial you need deposit:write and deposit:actions).

Important! Do not share your personal access token with anyone else, and only use it over HTTPS.

Using access tokens

A access token must be included in all requests as a URL parameter:

https://zenodo.org/api/deposit/depositions?access_token=ACCESS_TOKEN

Scopes

Scopes assigns permissions to your access token to limit access to data and actions in Zenodo. The following scopes exists:
Name Description
deposit:write Grants write access to depositions, but does not allow publishing the upload.
deposit:actions Grants access to publish, edit and discard edits for depositions.

Requests

The base URL of the API is https://zenodo.org/api/.

All POST and PUT request bodies must be JSON encoded, and must have content type of application/json unless specified otherwise in the specific resource (e.g. in the case of file uploads). The API will return a 415 error (see HTTP status codes and error responses) if the wrong content type is provided.

Responses

All response bodies are JSON encoded (UTF-8 encoded). A single resource is represented as a JSON object:

{
    "field1": value,
    ...
}

A collection of resources is represented as a JSON array of objects:

[
    {
        "field1": value,
        ...
    },
    ...
]

Timestamps are in UTC and formatted according to ISO 8601:

YYYY-MM-DDTHH:MM:SS+00:00

HTTP status codes

We use the following HTTP status codes to indicate success or failure of a request.
Code Name Description
200 OK Request succeeded. Response included. Usually sent for GET/PUT/PATCH requests.
201 Created Request succeeded. Response included. Usually sent for POST requests.
202 Accepted Request succeeded. Response included. Usually sent for POST requests, where background processing is needed to fulfill the request.
204 No Content Request succeeded. No response included. Usually sent for DELETE requests.
400 Bad Request Request failed. Error response included.
401 Unauthorized Request failed, due to an invalid access token. Error response included.
403 Forbidden Request failed, due to missing authorization (e.g. deleting an already submitted upload or missing scopes for your access token). Error response included.
404 Not Found Request failed, due to the resource not being found. Error response included.
405 Method Not Allowed Request failed, due to unsupported HTTP method. Error response included.
409 Conflict Request failed, due to the current state of the resource (e.g. edit a deopsition which is not fully integrated). Error response included.
415 Unsupported Media Type Request failed, due to missing or invalid request header Content-Type. Error response included.
429 Too Many Requests Request failed, due to rate limiting. Error response included.
500 Internal Server Error Request failed, due to an internal server error. Error response NOT included. Don't worry, Zenodo admins have been notified and will be dealing with the problem ASAP.

Errors

Error responses for 400 series errors (e.g. 400, 401, 403, ...) are returned as a JSON object with two attributes message and status (HTTP status code), and possibly an attribute errors with a list of more detailed errors.

Example of a simple error message without further detailed errors:

{
    "message": "Deposition not found",
    "status": 404
}

Example of an error message with additional detailed error messages:

{
    "message": "Validation error",
    "status": 400,
    "errors": [
        {"code": 10, "message":"Not a valid choice", "field": "access_right"}
    ]
}

The attribute errors is a JSON array of objects, with the attributes message and code, and possibly field for validation errors.

      OAI-PMH API use OAI-PMH to harvest Zenodo

      Zenodo allows you to harvest our entire repository via the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH). OAI-PMH is a widely used protocol for harvesting metadata and most popular repository software provide support for this protocol.

      All metadata is licensed under Creative Commons Zero, while the data files may be either open access and subject to a license described in the metadata or closed access and not available for download.

      Metadata formats

      Metadata for each record is available in several formats. The available formats include:
      oai_datacite3

      OAI DataCite — This metadata format has been specifically established for the dissemination of DataCite records using OAI-PMH. In addition to the original DataCite v3.0 metadata, this format contains several other elements describing the version of the metadata, whether it is of reference quality, and the registering datacentre. For more information about this format and its schema please see the DataCite OAI schema web site.

      Recommended We recommend you harvest using this metadata format. The format contains the most complete metadata and is our primary supported format.

      See example

      oai_datacite

      OAI DataCite — This metadata format has been specifically established for the dissemination of DataCite records using OAI-PMH. In addition to the original DataCite metadata, this format contains several other elements describing the version of the metadata, whether it is of reference quality, and the registering datacentre. For more information about this format and its schema please see the DataCite OAI schema web site.

      See example

      datacite3

      DataCite v3.0 — This metadata format contains only the original DataCite metadata without additions or alterations. The schema for this format does not exist and metadata will not validate against it. Please note that this format is not OAI-PMH version 2.0 compliant.

      See example

      datacite

      DataCite v2.2 — This metadata format contains only the original DataCite metadata without additions or alterations. The schema for this format does not exist and metadata will not validate against it. Please note that this format is not OAI-PMH version 2.0 compliant.

      Heads up! We will be upgrading to DataCite Metadata Schema v3.0 and discontinue support for DataCite v2.2, hence please ensure your OAI-PMH client are capable of reading both versions. There are only few backwards incompatible changes between v3.0 and v2.2.

      See example

      oai_dc

      Dublin Core — only minimal metadata is included in this format, and is primarily provided for clients which does not support oai_datacite.

      See example

      Sets

      We support both harvesting of the entire repository as well as selective harvesting of communities.

      user-zenodo

      All of Zenodo

      See example

      user-<identifier>

      Community sets — allows selective harvesting of specific communities. Replace <identifier> with the community identifier. Alternatively each community provides a direct harvesting API link on their front-page, which includes the correct community identifier.

      See example

      If you need selective harvesting and your use case is not supported by above sets, please contact us and we may possible set a specific set for you.

      Update schedule

      Sets are updated once an hour.

      Rate limit

      The OAI-PMH API is rated limited to one request per 2 seconds. We would be grateful if you notify us that you are harvesting us and in which context. It allows us to take your use case into consideration for future developments.

      Changes
